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

pub struct FnAbi<'a, Ty> {
    pub args: Vec<ArgAbi<'a, Ty>>,
    pub ret: ArgAbi<'a, Ty>,
    pub c_variadic: bool,
    pub fixed_count: usize,

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>>
Expand description

The LLVM types of each argument.

ret: ArgAbi<'a, Ty>
Expand description

LLVM return type.

c_variadic: boolfixed_count: usize
Expand description

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.
