Struct `std.uni.MatcherConcept`

Conceptual type that outlines the common properties of all UTF Matchers.



struct MatcherConcept
;

Properties

Name	Type	Description
`subMatcher`[get]	`auto`	Advanced feature - provide direct access to a subset of matcher based a set of known encoding lengths. Lengths are provided in code units. The sub-matcher then may do less operations per any `test`/`match`.

Methods

Name	Description
`match` (inp)	Perform a semantic equivalent 2 operations: decoding a code point at front of `inp` and testing if it belongs to the set of code points of this matcher.
`skip` (inp)	Perform a semantic equivalent 2 operations: decoding a code point at front of `inp` and testing if it belongs to the set of code points of this matcher.
`test` (inp)	Perform a semantic equivalent 2 operations: decoding a code point at front of `inp` and testing if it belongs to the set of code points of this matcher.

Note

For illustration purposes only, every method call results in assertion failure. Use utfMatcher to obtain a concrete matcher for UTF-8 or UTF-16 encodings.
