Enum Abi 

#[repr(u8)]
pub enum Abi {
    Rust = 0,
    C = 1,
    System = 2,
    Win64 = 3,
    Sysv64 = 4,
    Aapcs = 5,
    Cdecl = 6,
    Stdcall = 7,
    Fastcall = 8,
    Vectorcall = 9,
}

The abi or calling convention of a function pointer.

Variants

Rust = 0

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

C = 1

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

System = 2

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 = 3

The default for C code on x86_64 Windows.

Sysv64 = 4

The default for C code on non-Windows x86_64.

Aapcs = 5

The default for ARM.

Cdecl = 6

The default for x86_32 C code.

Stdcall = 7

The default for the Win32 API on x86_32.

Fastcall = 8

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

Vectorcall = 9

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.

impl Copy for Abi
