Expand description

Saturating arithmetic operations, returning maximum or minimum values instead of overflowing.

Required Methods§

source

fn saturating_add(self, rhs: Self) -> Self

Saturating addition. Compute `self + rhs`, saturating at the numeric bounds instead of overflowing.

source

fn saturating_sub(self, rhs: Self) -> Self

Saturating subtraction. Compute `self - rhs`, saturating at the numeric bounds instead of overflowing.

source

fn saturating_mul(self, rhs: Self) -> Self

Saturating multiply. Compute `self * rhs`, saturating at the numeric bounds instead of overflowing.

source

fn saturating_pow(self, exp: usize) -> Self

Saturating exponentiation. Compute `self.pow(exp)`, saturating at the numeric bounds instead of overflowing.

Provided Methods§

source

fn saturating_less_one(self) -> Selfwhere Self: One,

Decrement self by one, saturating at zero.

source

fn saturating_plus_one(self) -> Selfwhere Self: One,

Increment self by one, saturating at the numeric bounds instead of overflowing.

source

fn saturating_inc(&mut self)where Self: One,

Increment self by one, saturating.

source

fn saturating_dec(&mut self)where Self: One,

Decrement self by one, saturating at zero.

source

fn saturating_accrue(&mut self, amount: Self)where Self: One,

Increment self by some `amount`, saturating.

source

fn saturating_reduce(&mut self, amount: Self)where Self: One,

Decrement self by some `amount`, saturating at zero.
