}Expand description
Represents a counter type that wraps around when incremented past a
predetermined upper bound MAX (this bound is not exposed).
Required Methods
sourcefn wrapping_add_assign64(&mut self, rhs: u64) -> bool
fn wrapping_add_assign64(&mut self, rhs: u64) -> bool
Add a value to self. Returns true iff wrap-around has occurred.
rhs must be less than or equal to MAX.
sourcefn wrapping_add_assign128_multi32(&mut self, rhs: u128) -> u32
fn wrapping_add_assign128_multi32(&mut self, rhs: u128) -> u32
Add a value to self. Returns the number of times for which wrap-around
has occurred.
The result must not overflow.
