Expand description

Metadata describing how the arguments to a native function should be passed in order to respect the native ABI.

I will do my best to describe this structure, but these comments are reverse-engineered and may be inaccurate. -NDM

Fields

args: Vec<ArgAbi<'a, Ty>, Global>

The LLVM types of each argument.

ret: ArgAbi<'a, Ty>

LLVM return type.

c_variadic: boolfixed_count: usize

The count of non-variadic arguments.

Should only be different from args.len() when c_variadic is true. This can be used to know whether an argument is variadic or not.

conv: Convcan_unwind: bool

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.
