# 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`

:

`0-9`

`a-z`

`A-Z`

# Panics

This function panics if `radix`

is not in the range from 2 to 36.

# Examples

Basic usage:

assert_eq!(isize::from_str_radix("A", 16), Ok(10));Run

boundary of the type.

The only case where such wrapping can occur is when one divides `MIN / -1`

`MIN`

1.2.0 (const: 1.52.0)[src]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`

removes

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,

1.38.0 (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)`

.

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

is 0 or the division results in overflow.
