# Primitive Type usize1.0.0 [−]

The pointer-sized unsigned 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.

*See also the std::usize module.*

However, please note that examples are shared between primitive integer
types. So it's normal if you see usage of types like `isize`

in there.

1.2.0[src]

Wrapping (modular) division. Computes `self / other`

This function exists, so that all operations
are accounted for in the wrapping operations.

`fn wrapping_rem(self, rhs: usize) -> usize`

just the regular remainder calculation.
There's no way wrapping could ever happen.
This function exists, so that all operations
are accounted for in the wrapping operations.

`fn wrapping_neg(self) -> usize`

1.2.0[src]

Wrapping (modular) negation. Computes `-self`

,
wrapping around at the boundary of the type.

Since unsigned types do not have negative equivalents
all applications of this function will wrap (except for `-0`

).
For values smaller than the corresponding signed type's maximum
the result is the same as casting the corresponding signed value.
Any larger values are equivalent to `MAX + 1 - (val - MAX - 1)`

where
`MAX`

is the corresponding signed type's maximum.

# Examples

Basic usage:

assert_eq!(100u8.wrapping_neg(), 156); assert_eq!(0u8.wrapping_neg(), 0); assert_eq!(180u8.wrapping_neg(), 76); assert_eq!(180u8.wrapping_neg(), (127 + 1) - (180u8 - (127 + 1)));Run

`fn wrapping_shl(self, rhs: u32) -> usize`

1.2.0[src]

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!(1u8.wrapping_shl(7), 128); assert_eq!(1u8.wrapping_shl(8), 1);Run

`fn wrapping_shr(self, rhs: u32) -> usize`

1.2.0[src]

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.

integers overflow never occurs, so the second value is always
`false`

.

# Panics

This function will panic if `rhs`

is 0.

# Examples

Basic usage

assert_eq!(5u32.overflowing_div(2), (2, false));Run

`fn overflowing_rem(self, rhs: usize) -> (usize, bool)`

1.7.0[src]

Calculates the remainder when `self`

is divided by `rhs`

1.7.0[src]

Negates self in an overflowing fashion.

positive unsigned values overflow always occurs, but negating 0 does
not overflow.

`fn overflowing_shl(self, rhs: u32) -> (usize, bool)`

1.7.0[src]

Shifts self left by `rhs`

bits.

Returns a tuple of the shifted version of self along with a boolean indicating whether the shift value was larger than or equal to the number of bits. If the shift value is too large, then value is masked (N-1) where N is the number of bits, and this value is then used to perform the shift.

# Examples

Basic usage

assert_eq!(0x10u32.overflowing_shl(4), (0x100, false)); assert_eq!(0x10u32.overflowing_shl(36), (0x100, true));Run

`fn overflowing_shr(self, rhs: u32) -> (usize, bool)`

1.7.0[src]

Shifts self right by `rhs`

bits.

Returns a tuple of the shifted version of self along with a boolean indicating whether the shift value was larger than or equal to the number of bits. If the shift value is too large, then value is masked (N-1) where N is the number of bits, and this value is then used to perform the shift.

if and only if `self == 2^k`

for some `k`

`fn next_power_of_two(self) -> usize`

[src]

.

When return value overflows (i.e. `self > (1 << (N-1))`

for type
`uN`

), it panics in debug mode and return value is wrapped to 0 in
release mode (the only situation in which method can return 0).

# Examples

Basic usage:

assert_eq!(2u8.next_power_of_two(), 2); assert_eq!(3u8.next_power_of_two(), 4);Run

`fn checked_next_power_of_two(self) -> Option<usize>`
