Chainr1<E, A> class final

Right-associative binary operator chain: p (op p)* folded as a op (b op (c op d)).

The interpreter parses all elements and operators iteratively into two lists, then folds right at the end, so chain depth does not consume Dart call frames.

Properties

attempt → Parser<Never, Result<E, A>>

Available on Parser<E, A>, provided by the ParserOps extension

Run this parser, restoring position on failure. Returns the Result.
no setter
capture → Parser<E, String>

Available on Parser<E, A>, provided by the ParserOps extension

Run this parser and return the matched input as a string.
no setter
hashCode → int

no setterinherited
isSimple → bool
True if this parser cannot consume input on failure. Used to skip save/restore in Many/Choice/Or loops.
no setterinherited
