Enum AtomicClass 

pub enum AtomicClass {
    Bool,
    Int {
        bytes: u64,
        signed: bool,
    },
    Float {
        bytes: u64,
    },
    Ptr,
}

What kind of Rust atomic an object is reached through.

The width comes from the C type’s size, so long is an AtomicI64 on an LP64 target and an AtomicI32 on an ILP32 one; the data-model check is what makes that assumption safe.

Variants

Bool

_Bool, which is AtomicBool — a Rust bool may only ever hold 0 or 1, so it may not be reached through an integer atomic.

Int

An integer (or enum) of bytes bytes: AtomicI8 … AtomicU64.

Fields

bytes: u64

The width in bytes: 1, 2, 4 or 8.

signed: bool

Whether the C type is signed.

Float

float or double, reached through the integer atomic of the same width and to_bits/from_bits.

Fields

bytes: u64

The width in bytes: 4 or 8.

Ptr

An object pointer, which is AtomicPtr.

Implementations

impl AtomicClass

pub fn rust_name(self) -> &'static str

The name of the core::sync::atomic type.

pub fn repr_name(self) -> &'static str

The Rust primitive the atomic holds, which is what the pointer handed to from_ptr points at.
