Trait Abi 

pub trait Abi<I>:
    Copy
    + Debug
    + Hash
    + Eq
where
    I: Interner<Abi = Self>,
{
    // Required methods
    fn abi(self) -> Self;
    fn rust() -> Self;
    fn is_rust(self) -> bool;
    fn pack_abi(self) -> u8;
    fn unpack_abi(abi_index: u8) -> Self;
}

Required Methods

fn abi(self) -> Self

The identity function.

fn rust() -> Self

The ABI extern "Rust".

fn is_rust(self) -> bool

Whether this ABI is extern "Rust".

fn pack_abi(self) -> u8

Pack the ABI into a small dense integer, so it can be stored as packed FnSigKind flags.

fn unpack_abi(abi_index: u8) -> Self

Unpack the ABI from packed FnSigKind flags.

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.
