Methods

impl i64

pub const fn min_value() -> i64

Returns the smallest value that can be represented by this integer type.

Examples

Basic usage:

assert_eq!(i64::min_value(), -9223372036854775808);

pub const fn max_value() -> i64

pub fn from_str_radix(src: &str, radix: u32) -> Result<i64, ParseIntError>

Converts a string slice in a given base to an integer.

• A-Z

This function panics if radix is not in the range from 2 to 36.

pub fn wrapping_div(self, rhs: i64) -> i64

Wrapping (modular) division. Computes self / rhs, wrapping around at the boundary of the type.

The only case where such wrapping can occur is when one divides MIN / -1 on a signed type (where MIN is the negative minimal value for the type); this is equivalent to -MIN, a positive value that is too large to represent in the type. In such a case, this function returns MIN itself.

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

assert_eq!(100i64.wrapping_div(10), 10);

🔬 This is a nightly-only experimental API. (euclidean_division #49048)

Wrapping Euclidean division. Computes self.div_euc(rhs), wrapping around at the boundary of the type.

Wrapping will only occur in MIN / -1 on a signed type (where MIN is the negative minimal value for the type). This is equivalent to -MIN, a positive value that is too large to represent in the type. In this case, this method returns MIN itself.

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

pub fn wrapping_rem(self, rhs: i64) -> i64

Such wrap-around never actually occurs mathematically; implementation artifacts make x % y invalid for MIN / -1 on a signed type (where MIN is the negative minimal value). In such a case, this function returns 0.

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

assert_eq!(100i64.wrapping_rem(10), 0);
assert_eq!((-128i8).wrapping_rem(-1), 0);

pub fn wrapping_neg(self) -> i64

Wrapping (modular) negation. Computes -self, wrapping around at the boundary of the type.

The only case where such wrapping can occur is when one negates MIN on a signed type (where MIN is the negative minimal value for the type); this is a positive value that is too large to represent in the type. In such a case, this function returns MIN itself.

Examples

Basic usage:

assert_eq!(i64::min_value().wrapping_neg(), i64::min_value());

pub fn wrapping_shl(self, rhs: u32) -> i64

Panic-free bitwise shift-left; yields self << mask(rhs), where mask removes any high-order bits of rhs that would cause the shift to exceed the bitwidth of the type.

Note that this is not the same as a rotate-left; the RHS of a wrapping shift-left is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a rotate_left function, which may be what you want instead.

Examples

Basic usage:

assert_eq!((-1i64).wrapping_shl(7), -128);
assert_eq!((-1i64).wrapping_shl(128), -1);

pub fn wrapping_shr(self, rhs: u32) -> i64

Panic-free bitwise shift-right; yields self >> mask(rhs), where mask removes any high-order bits of rhs that would cause the shift to exceed the bitwidth of the type.

Note that this is not the same as a rotate-right; the RHS of a wrapping shift-right is restricted to the range of the type, rather than the bits shifted out of the LHS being returned to the other end. The primitive integer types all implement a rotate_right function, which may be what you want instead.

Examples

Basic usage:

The only case where such wrapping can occur is when one takes the absolute value of the negative minimal value for the type this is a positive value that is too large to represent in the type. In such a case, this function returns MIN itself.

Examples

Basic usage:

assert_eq!(100i64.wrapping_abs(), 100);
assert_eq!((-100i64).wrapping_abs(), 100);
assert_eq!(i64::min_value().wrapping_abs(), i64::min_value());

let a: i64 = 7; // or any other integer type
let b = 4;

assert_eq!(a.mod_euc(b), 3);
assert_eq!((-a).mod_euc(b), 1);
assert_eq!(a.mod_euc(-b), 3);
assert_eq!((-a).mod_euc(-b), 1);

pub fn abs(self) -> i64

Computes the absolute value of self.

Overflow behavior

The absolute value of i64::min_value() cannot be represented as an i64, and attempting to calculate it will cause an overflow. This means that code in debug mode will trigger a panic on this case and optimized code will return i64::min_value() without a panic.

Examples

Basic usage:

assert_eq!(10i64.abs(), 10);
assert_eq!((-10i64).abs(), 10);

pub fn signum(self) -> i64

Returns a number representing sign of self.

• 0 if the number is zero
• 1 if the number is positive
• -1 if the number is negative

Examples

Basic usage:

assert_eq!(10i64.signum(), 1);
assert_eq!(0i64.signum(), 0);
assert_eq!((-10i64).signum(), -1);

pub fn is_positive(self) -> bool

Returns true if self is positive and false if the number is zero or negative.

Examples

Basic usage:

assert!(10i64.is_positive());
assert!(!(-10i64).is_positive());

pub fn is_negative(self) -> bool

Returns true if self is negative and false if the number is zero or positive.

Examples

Basic usage:

assert!((-10i64).is_negative());
assert!(!10i64.is_negative());

pub fn to_bytes(self) -> [u8; 8]

🔬 This is a nightly-only experimental API. (int_to_from_bytes #49792)

Return the memory representation of this integer as a byte array.

The target platform’s native endianness is used. Portable code likely wants to use this after to_be or to_le.

Examples

#![feature(int_to_from_bytes)]

let bytes = i32::min_value().to_be().to_bytes();
assert_eq!(bytes, [0x80, 0, 0, 0]);

pub fn from_bytes(bytes: [u8; 8]) -> i64

🔬 This is a nightly-only experimental API. (int_to_from_bytes #49792)

Create an integer value from its memory representation as a byte array.

The target platform’s native endianness is used. Portable code likely wants to use from_be or from_le after this.

Examples

#![feature(int_to_from_bytes)]

let int = i32::from_be(i32::from_bytes([0x80, 0, 0, 0]));
assert_eq!(int, i32::min_value());
