Enum stable_mir::abi::PassMode

pub enum PassMode {
    Ignore,
    Direct(Opaque),
    Pair(Opaque, Opaque),
    Cast {
        pad_i32: bool,
        cast: Opaque,

How a function argument should be passed in to the target function.

Variants

Ignore

Ignore the argument.

The argument is either uninhabited or a ZST.

Direct(Opaque)

Pass the argument directly.

The argument has a layout abi of Scalar or Vector.

Pair(Opaque, Opaque)

Pass a pair’s elements directly in two arguments.

The argument has a layout abi of ScalarPair.

Cast

Pass the argument after casting it.

Fields

pad_i32: bool

cast: Opaque

Indirect

Pass the argument indirectly via a hidden pointer.

Fields

attrs: Opaque

meta_attrs: Opaque

on_stack: bool

Trait Implementations

impl Clone for PassMode

fn clone(&self) -> PassMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PassMode

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

Formats the value using the given formatter.

impl Hash for PassMode

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 PassMode

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

impl Eq for PassMode

impl StructuralPartialEq for PassMode

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.
