Summarizes information

Variants

Arg(String, String)
Expand description

An argument of non-tuple type. Parameters are (name, ty)

Tuple(Option<Span>, Vec<(String, String)>)
Expand description

An argument of tuple type. For a “found” argument, the span is the location in the source of the pattern. For a “expected” argument, it will be None. The vector is a list of (name, ty) strings for the components of the tuple.

Implementations

impl ArgKind[src]

fn empty() -> ArgKind[src]

pub fn from_expected_ty(t: Ty<'_>, span: Option<Span>) -> ArgKind[src]
