Struct ParseRecoveryTokenSet 

pub struct ParseRecoveryTokenSet<K: SyntaxKind> { /* private fields */ }

Recovers the parser by finding a token/point (depending on the configuration) from where the caller knows how to proceed parsing. The recovery wraps all the skipped tokens inside a Bogus node. A safe recovery point for an array element could by finding the next , or ].

Implementations

impl<K: SyntaxKind> ParseRecoveryTokenSet<K>

pub fn new(node_kind: K, recovery_set: TokenSet<K>) -> Self

Creates a new parse recovery that eats all tokens until it finds any token in the passed recovery set.

pub fn enable_recovery_on_line_break(self) -> Self

Enable recovery on line breaks

pub fn recover<P>(&self, p: &mut P) -> RecoveryResult

where P: Parser<Kind = K>,

Tries to recover by parsing all tokens into an Bogus* node until the parser finds any token specified in the recovery set, the EOF, or a line break (depending on configuration). Returns Ok(bogus_node) if recovery was successful, and Err(RecoveryError::Eof) if the parser is at the end of the file (before starting recovery).
