pub fn text(self) -> &'static [u8]

Returns the canonical upper-case spelling of the keyword.

pub fn may_fall_back(self) -> bool

Returns whether the keyword may stand in for an identifier.

SQLite declares a fallback set so that historical schemas using words like KEY or MATCH as column names keep working. A word outside the set is a hard keyword in every position.

impl Keyword

pub const JOIN_KEYWORDS: &'static [Keyword]

SQLite’s JOIN_KW token class: the words that introduce a join.

They are hard keywords in the sense that matters to may_fall_back - none appears in the %fallback declaration - and they are still legal names, because the name production accepts the token class directly. Both facts are true at once and the grammar states them separately.

pub fn as_str(self) -> &'static str

Returns the canonical spelling as text, for diagnostics.

pub fn is_join_keyword(self) -> bool

Returns whether the keyword introduces a join.

pub fn may_be_name(self) -> bool

Returns whether the keyword may be written where a name is expected.

This is SQLite’s nm ::= idj | STRING with idj ::= ID|INDEXED|JOIN_KW, so it is the fallback set plus the seven join keywords plus INDEXED. It is the right question for a column declaration, a table or index name, a qualified reference, a window name, and an alias written with AS.

It is the wrong question for the two positions that take ids - a bare alias and a declared type name - which take only Keyword::may_fall_back; see this module’s header for why the two cannot be merged.
