Struct std.uni.MatcherConcept

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

struct MatcherConcept ;

Properties

NameTypeDescription
subMatcher[get] autoAdvanced 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

NameDescription
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.
