Implementations§
Source§impl TokenKind
impl TokenKind
Sourcepub fn is_keyword_or_identifier(&self) -> bool
pub fn is_keyword_or_identifier(&self) -> bool
Returns true for keyword and identifier kinds.
Numeric kinds (Integer / Float) are excluded here: the word
spellings FLOAT / INTEGER (field-type keywords mapped onto those
kinds) are recovered by Token::is_keyword_or_identifier.
Sourcepub fn is_statement_start(&self) -> bool
pub fn is_statement_start(&self) -> bool
Keywords that open a top-level statement (parse_stmt match arms).
Sourcepub fn is_recovery_sync(&self) -> bool
pub fn is_recovery_sync(&self) -> bool
Panic-mode sync tokens after a parse error.
WITH is omitted: it is both a CTE opener and a clause (WITH PAYLOAD,
WITH PARAMS), so treating it as a boundary would split a query at the
clause. Missing-semicolon recovery still uses Self::is_statement_start.
