delimited | Parse a token stream that starts with start and ends with end , returning
all of the tokens in between. The tokens in between must match cond .
Succeeds even if there are no tokens between start and end .
|
delimited_some | Parse a token stream that starts with start and ends with end , returning
all of the tokens in between. The tokens in between must match cond . There
must be at least one token between start and end .
|
eat | Eats the current token if it is token .
|
eat_any | Eats the current token unconditionally. Fails if there are no tokens.
|
eat_if | Eats the token token if cond holds on the current token.
|
eat_slice | Eats the current slice if it is slice .
|
enclosed | Like delimited but keeps the start and end .
|
eof | Succeeds only if the input has reached EOF.
|
none | Consumes no tokens. Always succeeds. Equivalent to take_while(|_| false) .
|
peek | Succeeds if the current token is token .
|
peek_any | Returns the current token.
|
peek_if | Succeeds if cond holds for the current token.
|
peek_if_copy | Succeeds if cond holds for the current token.
|
peek_slice | Succeeds if the current slice is slice .
|
peek_slice_if | Succeeds if the current slice is slice .
|
skip_any | Skips the current token unconditionally. Fails if there are no tokens.
|
skip_while | Skips tokens while cond matches.
|
take_n | Takes at most n tokens.
|
take_n_if | Take exactly n tokens, ensuring cond holds on all n .
|
take_n_while | Takes at most n tokens as long as cond holds.
|
take_some_while | Consumes tokens while cond matches and returns them. Succeeds only if at
least one token matched cond .
|
take_some_while_some_window | Consumes tokens while cond matches on a window of tokens of size n and
returns them. Fails if there aren’t at least n tokens or if no tokens
match, otherwise returns all of the tokens before the first failure.
|
take_some_while_until | Consumes tokens while cond matches and the token is not until . Succeeds
only if at least one token matched cond .
|
take_some_while_window | Consumes tokens while cond matches on a window of tokens of size n and
returns them. Fails if there no tokens match, otherwise returns all of the
tokens before the first failure.
|
take_until_slice | Consumes tokens while cond matches on a window of tokens of size n and
returns them. Succeeds even if no tokens match.
|
take_while | Consumes tokens while cond matches and returns them. Succeeds even if no
tokens match.
|
take_while_slice | Consumes tokens while cond matches on a continously growing slice
beginning at a length of 0 and ending when cond fails. Returns the slice
between 0 and cond failing. Errors if no such slice exists.
|
take_while_some_window | Consumes tokens while cond matches on a window of tokens of size n and
returns them. Fails if there aren’t at least n tokens, otherwise always
otherwise always succeeds. If no tokens match, the result will be empty.
|
take_while_until | Consumes tokens while cond matches and the token is not until . Succeeds
even if no tokens match.
|
take_while_window | Consumes tokens while cond matches on a window of tokens of size n and
returns all of the tokens prior to the first failure to match. For example,
given a string of “aaab” and a size 2 window predicate of window == "aa" ,
the return value is "aa" as the first failure to match is at "ab" .
