Primitive Type isize1.0.0[−]
Expand description
The pointer-sized signed integer type.
The size of this primitive is how many bytes it takes to reference any location in memory. For example, on a 32 bit target, this is 4 bytes and on a 64 bit target, this is 8 bytes.
Implementations
impl isize[src]
impl isize[src]pub fn from_str_radix(src: &str, radix: u32) -> Result<isize, ParseIntError>[src]
pub fn from_str_radix(src: &str, radix: u32) -> Result<isize, ParseIntError>[src]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:
0-9a-zA-Z
Panics
This function panics if radix is not in the range from 2 to 36.
Examples
Basic usage:
assert_eq!(isize::from_str_radix("A", 16), Ok(10));Run

#[must_use = "this returns the result of the operation, \ without modifying the original"]pub const fn wrapping_div(self, rhs: isize) -> isize1.2.0 (const: 1.52.0)[src]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.

This function will panic if rhs is 0.

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.

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
Basic usage:

Wrapping will only occur in MIN % -1 on a signed type (where MIN is the negative minimal value
for the type). In this case, this method returns 0.
Panics
This function will panic if rhs is 0.

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.

#[must_use = "this returns the result of the operation, \ without modifying the original"]pub const fn div_euclid(self, rhs: isize) -> isize1.38.0 (const: 1.52.0)[src]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: isize = 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 * 2Run

#[must_use = "this returns the result of the operation, \ without modifying the original"]pub const fn rem_euclid(self, rhs: isize) -> isize1.38.0 (const: 1.52.0)[src]Calculates the least nonnegative remainder of self (mod rhs).
This is done as if by the Euclidean division algorithm – given
r = self.rem_euclid(rhs), self = rhs * self.div_euclid(rhs) + r, and
0 <= r < abs(rhs).
Panics
This function will panic if rhs is 0 or the division results in overflow.
Examples
Basic usage:
let a: isize = 7; // or any other integer type let b = 4; assert_eq!(a.rem_euclid(b), 3); assert_eq!((-a).rem_euclid(b), 1); assert_eq!(a.rem_euclid(-b), 3); assert_eq!((-a).rem_euclid(-b), 1);Run

Overflow behavior
The absolute value of
isize::MIN
cannot be represented as an
isize,
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
isize::MIN
without a panic.
