Expand description

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

Trait Implementations

Gets the LLVM type for a place of the original Rust type of this argument/return, i.e., the result of type_of::type_of.

Stores a direct/indirect value described by this ArgAbi into a place for the original Rust type of this argument/return. Can be used for both storing formal arguments into Rust variables or results of call/invoke instructions into their destinations.

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

The type returned in the event of a conversion error.

Performs the conversion.

The type returned in the event of a conversion error.

Performs the conversion.

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.
