Struct RAngle

pub(crate) struct RAngle;

There are some lexing ambiguities with >> which can represet both a right shift or two closing angle brackets in nested generics (e.g., Vec<Option<i32>>). We solve the ambiguity by giving > a special token if it’s immediately followed by another >, i.e., >> is tokenized as Token::GtFollowedByGt followed by Token::Gt.

Use this struct to match on a right angle bracket for the purpose of parsing generics.

Trait Implementations

impl Clone for RAngle

fn clone(&self) -> RAngle

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Peek for RAngle

fn matches(self, tok: Token) -> bool

Returns true if a token matches this rule

fn display(self) -> impl Iterator<Item = &'static str>

A string representation of the list of tokens matched by this rule. This is used to construct an error when using Lookahead1.
