[−][src]Struct rustc_ap_rustc_target::abi::call::FnAbi

pub struct FnAbi<'a, Ty> {
    pub args: Vec<ArgAbi<'a, Ty>>,
    pub ret: ArgAbi<'a, Ty>,

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>>

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
