API not fully fleshed out and ready to be stabilized

[−] Expand description

Expresses that a match of the pattern has been found at haystack[a..b].

Reject(usize, usize)

🔬 This is a nightly-only experimental API. (pattern #27721)

API not fully fleshed out and ready to be stabilized

[−] Expand description

Expresses that haystack[a..b] has been rejected as a possible match of the pattern.

Note that there might be more than one Reject between two Matches, there is no requirement for them to be combined into one.
