Enum rustc_session::cstore::DllCallingConvention

pub enum DllCallingConvention {
    C,
    Stdcall(usize),
    Fastcall(usize),
    Vectorcall(usize),
}

Calling convention for a function defined in an external library.

The usize value, where present, indicates the size of the function’s argument list in bytes.

Variants

C

Stdcall(usize)

Fastcall(usize)

Vectorcall(usize)

Trait Implementations

impl Clone for DllCallingConvention

fn clone(&self) -> DllCallingConvention

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DllCallingConvention

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

Formats the value using the given formatter.

impl<__D: SpanDecoder> Decodable<__D> for DllCallingConvention

fn decode(__decoder: &mut __D) -> Self

impl<__E: SpanEncoder> Encodable<__E> for DllCallingConvention

fn encode(&self, __encoder: &mut __E)

impl<__CTX> HashStable<__CTX> for DllCallingConvention

where __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl PartialEq for DllCallingConvention

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

This method tests for self and other values to be equal, and is used by ==.

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

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

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.

Size: 16 bytes

Size for each variant:

• C: 0 bytes
• Stdcall: 8 bytes
