Enum Abi 

pub enum Abi {
    Rust,
    C,
    System,
    Win64,
    Sysv64,
    Aapcs,
    Cdecl,
    Stdcall,
    Fastcall,
    Vectorcall,
}

The abi or calling convention of a function pointer.

Variants

Rust

The default ABI when you write a normal fn foo() in any Rust code.

C

This is the same as extern fn foo(); whatever the default your C compiler supports.

System

Usually the same as extern "C", except on Win32, in which case it’s "stdcall", or what you should use to link to the Windows API itself.

Win64

The default for C code on x86_64 Windows.

Sysv64

The default for C code on non-Windows x86_64.

Aapcs

The default for ARM.

Cdecl

The default for x86_32 C code.

Stdcall

The default for the Win32 API on x86_32.

Fastcall

The fastcall ABI – corresponds to MSVC’s __fastcall and GCC and clang’s __attribute__((fastcall))

Vectorcall

The vectorcall ABI – corresponds to MSVC’s __vectorcall and GCC and clang’s __attribute__((vectorcall))

Implementations

impl Abi

pub const fn to_str(&self) -> &'static str

Returns the string representation of this ABI.

impl Abi

pub fn is_alias(&self) -> bool

Returns true if this ABI is an alias.

pub fn is_concrete(&self) -> bool

Returns true if this ABI is a concrete ABI, not an alias.

pub fn concrete(&self) -> Abi

Returns the concrete ABI for this ABI on the current target.

Trait Implementations

impl Clone for Abi

fn clone(&self) -> Abi

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Abi

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for Abi

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for Abi

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for Abi

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Abi

fn eq(&self, other: &Abi) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
