Methods

`impl i32`
[src]

`pub const fn min_value() -> i32`
[src]

a-z
a-z

`pub fn wrapping_div(self, rhs: i32) -> i32`
1.2.0
[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.

Panics

This function will panic if rhs is 0.

Examples

Basic usage:

assert_eq!((-128i8).wrapping_div(-1), -128);Run

`pub fn wrapping_rem(self, rhs: i32) -> i32`
1.2.0
[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 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!(100i32.wrapping_rem(10), 0);
assert_eq!((-128i8).wrapping_rem(-1), 0);Run

`pub fn wrapping_neg(self) -> i32`
1.2.0
[src]

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!(100i32.wrapping_neg(), -100);
assert_eq!(i32::min_value().wrapping_neg(), i32::min_value());Run

`pub fn wrapping_shl(self, rhs: u32) -> i32`
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!((-1i32).wrapping_shl(7), -128);
assert_eq!((-1i32).wrapping_shl(128), -1);Run

`pub fn wrapping_shr(self, rhs: u32) -> i32`
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.

Examples

assert_eq!((-128i16).wrapping_shr(64), -128);Run

`pub fn wrapping_abs(self) -> i32`
1.13.0
[src]

Wrapping (modular) absolute value. Computes self.abs(), wrapping around at the boundary of the type.

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!(100i32.wrapping_abs(), 100);
assert_eq!((-100i32).wrapping_abs(), 100);
assert_eq!(i32::min_value().wrapping_abs(), i32::min_value());

1.13.0
[src]

Computes the absolute value of self.

[src]

Overflow behavior

The absolute value of i32::min_value() cannot be represented as an i32, 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 i32::min_value() without a panic.
