Implementations§

Source §

impl UnevaluatedKind

Source

pub(crate) fn name(self) -> &'static str

The marker’s type name, for diagnostics.

Source

pub(crate) fn r_call_arg(self, p: &str) -> String

The .Call() argument the R wrapper passes for parameter p: the missing-argument sentinel, as for Missing<T>, else the capture. Never forces p.

Source

pub(crate) fn api_path(self) -> TokenStream

The marker’s path in miniextendr_api.

Source

fn of_segment(seg: &PathSegment) -> Option<Self>

The marker a path segment names: Quoted / Quosure, bare or with lifetime arguments only (Quoted<'_>).
