Expand description

Information about how to pass an argument to, or return a value from, a function, under some ABI.

## Fields§

## Implementations§

source§

### impl<'a, Ty> ArgAbi<'a, Ty>

source

#### pub fn new( cx: &impl HasDataLayout, layout: TyAndLayout<'a, Ty>, scalar_attrs: impl Fn(&TyAndLayout<'a, Ty>, Scalar, Size) -> ArgAttributes ) -> Self

This defines the “default ABI” for that type, that is then later adjusted in `fn_abi_adjust_for_abi`.

source

#### fn indirect_pass_mode(layout: &TyAndLayout<'a, Ty>) -> PassMode

source

#### pub fn make_direct_deprecated(&mut self)

Pass this argument directly instead. Should NOT be used! Only exists because of past ABI mistakes that will take time to fix (see https://github.com/rust-lang/rust/issues/115666).

source

#### pub fn make_indirect(&mut self)

source

#### pub fn make_indirect_byval(&mut self, byval_align: Option<Align>)

source

#### pub fn extend_integer_width_to(&mut self, bits: u64)

source

#### pub fn cast_to<T: Into<CastTarget>>(&mut self, target: T)

source

#### pub fn cast_to_and_pad_i32<T: Into<CastTarget>>( &mut self, target: T, pad_i32: bool )

source

#### pub fn is_indirect(&self) -> bool

source

#### pub fn is_sized_indirect(&self) -> bool

source

#### pub fn is_unsized_indirect(&self) -> bool

source

#### pub fn is_ignore(&self) -> bool

source

#### pub fn eq_abi(&self, other: &Self) -> bool

Checks if these two `ArgAbi` are equal enough to be considered “the same for all function call ABIs”.

## Layout§

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
