Struct SigArg 

pub struct SigArg {
    pub name: &'static str,
    pub params: Option<&'static [Param]>,
}

One Rust argument of a native function.

params == None: one positional-only parameter named name. Some(ps): the type supplies ps and name is ignored. Some(&[]): the argument contributes nothing.

Fields

name: &'static str

params: Option<&'static [Param]>

Implementations

impl SigArg

pub const fn from_arg<T: FromArgs>(name: &'static str) -> Self

pub const fn marker(name: &'static str) -> Self

$self / $type receiver marker. Renders as one positional-only parameter.

pub const fn implicit<T: FromArgs>() -> Self

Parameters supplied by the argument a method binds as its receiver. None metadata contributes nothing, so this never looks nameless.
