Implementations

impl SequenceExpr

pub fn any_capitalization_of(word: &'static str) -> Self

Construct a new sequence with a Word at the beginning of the operation list.

pub fn aco(word: &'static str) -> Self

Shorthand for Self::any_capitalization_of.

pub fn any_of(exprs: Vec<Box<dyn Expr>>) -> Self

Match the first of multiple expressions.

pub fn word_set(words: &'static [&'static str]) -> Self

Match any word from the given set of words, case-insensitive.

pub fn then(self, expr: impl Expr + 'static) -> Self

Push an expression to the operation list.

pub fn then_optional(self, expr: impl Expr + 'static) -> Self

Pushes an expression that could move the cursor to the sequence, but does not require it.

pub fn then_any_of(self, exprs: Vec<Box<dyn Expr>>) -> Self

Pushes an expression that will match any of the provided expressions.

If more than one of the provided expressions match, this function provides no guarantee as to which match will end up being used. If you need to get the longest of multiple matches, use Self::then_longest_of() instead.

pub fn then_longest_of(self, exprs: Vec<Box<dyn Expr>>) -> Self

Pushes an expression that will match the longest of the provided expressions.

If you don’t need the longest match, prefer using the short-circuiting Self::then_any_of() instead.

pub fn then_seq(self, other: Self) -> Self

Appends the steps in other onto the end of self. This is more efficient than Self::then because it avoids pointer redirection.

pub fn then_word_set(self, words: &'static [&'static str]) -> Self

Pushes an expression that will match any word from the given set of words, case-insensitive.

pub fn then_strict(self, kind: TokenKind) -> Self

Matches any token whose Kind exactly matches.

pub fn then_whitespace(self) -> Self

Match against one or more whitespace tokens.

pub fn t_ws(self) -> Self

Shorthand for Self::then_whitespace.

pub fn then_one_or_more(self, expr: impl Expr + 'static) -> Self

pub fn then_unless(self, condition: impl Expr + 'static) -> Self

Create a new condition that will step one token forward if met. If the condition is not met, the whole expression returns None.

This can be used to build out exceptions to other rules.

See UnlessStep for more info.

Match any single token.

See AnyPattern for more info.
