Enum Abi

pub enum Abi {
    Rust,
    C {
        unwind: bool,
    },
    Cdecl {
        unwind: bool,
    },
    Stdcall {
        unwind: bool,
    },
    Fastcall {
        unwind: bool,
    },
    Aapcs {
        unwind: bool,
    },
    Win64 {
        unwind: bool,
    },
    SysV64 {
        unwind: bool,
    },
    System {
        unwind: bool,
    },
    Other(String),
}

The ABI (Application Binary Interface) used by a function.

If a variant has an unwind field, this means the ABI that it represents can be specified in 2 ways: extern "_" and extern "_-unwind", and a value of true for that field signifies the latter variant.

See the Rustonomicon section on unwinding for more info.

Variants

Rust

The default ABI, but that can also be written explicitly with extern "Rust".

C

Can be specified as extern "C" or, as a shorthand, just extern.

Fields

unwind: bool

Cdecl

Can be specified as extern "cdecl".

Fields

unwind: bool

Stdcall

Can be specified as extern "stdcall".

Fields

unwind: bool

Fastcall

Can be specified as extern "fastcall".

Fields

unwind: bool

Aapcs

Can be specified as extern "aapcs".

Fields

unwind: bool

Win64

Can be specified as extern "win64".

Fields

unwind: bool

SysV64

Can be specified as extern "sysv64".

Fields

unwind: bool

System

Can be specified as extern "system".

Fields

unwind: bool

Other(String)

Any other ABI, including unstable ones.

Trait Implementations

impl Clone for Abi

fn clone(&self) -> Abi

Returns a copy 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<'de> Deserialize<'de> for Abi

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 Serialize for Abi

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Abi

impl StructuralPartialEq for Abi

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
