Trait Counter

pub trait Counter:
    Default
    + Sized
    + From<u8>
    + TryFrom<u32>
    + TryFrom<usize> {
    // Required methods
    fn checked_add_assign(&mut self, rhs: Self) -> Result<(), Overflowed>;
    fn checked_mul(self, rhs: Self) -> Result<Self, Overflowed>;
    fn byte_aligned(&self) -> bool;
}

A common trait for integer types for performing math operations which may check for overflow.

Required Methods

fn checked_add_assign(&mut self, rhs: Self) -> Result<(), Overflowed>

add rhs to self, returning Overflowed if the result is too large

fn checked_mul(self, rhs: Self) -> Result<Self, Overflowed>

multiply self by rhs, returning Overflowed if the result is too large

fn byte_aligned(&self) -> bool

returns true if the number if bits written is divisible by 8

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
