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: Box<[ArgAbi<'a, Ty>]>
The LLVM types of each argument.
ret: ArgAbi<'a, Ty>
LLVM return type.
c_variadic: bool
§fixed_count: u32
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: Conv
§can_unwind: bool

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.
