Trait PrimitiveAtomicInteger 

pub trait PrimitiveAtomicInteger: PrimitiveAtomic {
    const BITS: u32;

    // Required methods
    fn fetch_add(&self, val: Self::Value, order: Ordering) -> Self::Value;
    fn fetch_sub(&self, val: Self::Value, order: Ordering) -> Self::Value;
    fn fetch_max(&self, val: Self::Value, order: Ordering) -> Self::Value;
    fn fetch_min(&self, val: Self::Value, order: Ordering) -> Self::Value;
}

Trait for all primitive atomic integer types, extending PrimitiveAtomic.

This adds integer-specific atomic operations: fetch_add, fetch_sub, fetch_max, fetch_min, and a BITS constant.

This trait is sealed to prevent downstream implementations.

Required Associated Constants

const BITS: u32

The size of this atomic integer type in bits.

Required Methods

fn fetch_add(&self, val: Self::Value, order: Ordering) -> Self::Value

Adds to the current value, returning the previous value.

fn fetch_sub(&self, val: Self::Value, order: Ordering) -> Self::Value

Subtracts from the current value, returning the previous value.

fn fetch_max(&self, val: Self::Value, order: Ordering) -> Self::Value

Stores the maximum of the current value and val. Returns the previous value.

fn fetch_min(&self, val: Self::Value, order: Ordering) -> Self::Value

Stores the minimum of the current value and val. Returns the previous value.

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.
