Struct rustc_target::abi::call::ArgAbi

pub struct ArgAbi<'a, Ty> {
    pub layout: TyAndLayout<'a, Ty>,
    pub pad: Option<Reg>,
    pub mode: PassMode,
}

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

Fields

layout: TyAndLayout<'a, Ty>

pad: Option<Reg>

Dummy argument, which is emitted before the real argument.

mode: PassMode

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

Formats the value using the given formatter.

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.
