Implementations
sourceimpl i64
impl i64
sourcepub fn from_str_radix(src: &str, radix: u32) -> Result<Self, ParseIntError>
pub fn from_str_radix(src: &str, radix: u32) -> Result<Self, ParseIntError>
Converts a string slice in a given base to an integer.
The string is expected to be an optional +
or -
sign followed by digits.
Leading and trailing whitespace represent an error. Digits are a subset of these characters,
depending on radix
:
0-9
a-z
A-Z
Panics
This function panics if radix
is not in the range from 2 to 36.
Examples
Basic usage:
assert_eq!(i64::from_str_radix("A", 16), Ok(10));

pub const fn wrapping_div(self, rhs: Self) -> Self
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:

pub const fn wrapping_div_euclid(self, rhs: Self) -> Self
Wrapping Euclidean division. Computes self.div_euclid(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.

pub const fn wrapping_rem(self, rhs: Self) -> Self
Wrapping (modular) remainder. Computes self % rhs
, wrapping around at the
boundary of the type.
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

Run1.2.0 (const: 1.32.0) · sourcepub const fn wrapping_shl(self, rhs: u32) -> Self
pub const fn wrapping_shl(self, rhs: u32) -> Self
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.

1.38.0 (const: 1.52.0) · sourcepub const fn div_euclid(self, rhs: Self) -> Self
pub const fn div_euclid(self, rhs: Self) -> Self
Calculates the quotient of Euclidean division of self
by rhs
.
This computes the integer q
such that self = q * rhs + r
, with
r = self.rem_euclid(rhs)
and 0 <= r < abs(rhs)
.
In other words, the result is self / rhs
rounded to the integer q
such that self >= q * rhs
.
If self > 0
, this is equal to round towards zero (the default in Rust);
if self < 0
, this is equal to round towards +/- infinity.
Panics
This function will panic if rhs
is 0 or the division results in overflow.
Examples
Basic usage:
let a: i64 = 7; // or any other integer type
let b = 4;
assert_eq!(a.div_euclid(b), 1); // 7 >= 4 * 1
assert_eq!(a.div_euclid(-b), -1); // 7 >= -4 * -1
assert_eq!((-a).div_euclid(b), -2); // -7 >= 4 * -2
assert_eq!((-a).div_euclid(-b), 2); // -7 >= -4 * 2

const: unstable · sourceimpl Rem<i64> for i64
impl Rem<i64> for i64
This operation satisfies n % d == n - (n / d) * d
. The
result has the same sign as the left operand.
Panics
This operation will panic if other == 0
or if self / other
results in overflow.
