Enum rustc_codegen_llvm::abi::ArgExtension

pub(crate) enum ArgExtension {
    None,
    Zext,
    Sext,
}

Sometimes an ABI requires small integers to be extended to a full or partial register. This enum defines if this extension should be zero-extension or sign-extension when necessary. When it is not necessary to extend the argument, this enum is ignored.

Trait Implementations

impl Clone for ArgExtension

fn clone(&self) -> ArgExtension

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ArgExtension

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

Formats the value using the given formatter.

impl Hash for ArgExtension

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

where __H: Hasher,

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<__CTX> HashStable<__CTX> for ArgExtension

where __CTX: HashStableContext,

fn hash_stable( &self, __hcx: &mut __CTX, __hasher: &mut StableHasher<SipHasher128>, )

impl PartialEq for ArgExtension

fn eq(&self, other: &ArgExtension) -> 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.

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.
