GeneratedMatch

Struct GeneratedMatch 

Source
pub struct GeneratedMatch { /* private fields */ }
Expand description

Outcome of a generated token / set / not-set match that may recover.

Generated parsers append children to the current rule context. consumed_eof reports whether the match actually consumed a real EOF terminal — it is true only on a successful match (or single-token deletion that lands on EOF), and always false on single-token insertion, which synthesizes a missing token and consumes nothing. Generated code feeds this into finish_rule’s consumed_eof, so the rule stop token is recorded as EOF only when EOF was truly matched, matching ANTLR’s matchedEOF semantics.

Implementations§

Source§

impl GeneratedMatch

Source

pub fn children(&self) -> &[ParseTree]

Parse-tree children produced by the match (the matched terminal, an error node plus deleted-then-matched terminal, or a single missing-token error node).

Source

pub fn into_children(self) -> Vec<ParseTree>

Consumes the result, returning the children for appending to the rule context.

Source

pub const fn consumed_eof(&self) -> bool

Whether a real EOF terminal was consumed by this match.
