Enum member `std.regex.ctRegex`

Compile regular expression using CTFE and generate optimized native machine code for matching it.


						
				enum ctRegex(alias pattern, string flags = "") = ctRegexImpl!(pattern, flags).wrapper;

Note

Unlike regex, ctRegex always uses a backtracking engine, even for patterns without backreferences. This means matching is not guaranteed to run in linear time. For patterns applied to untrusted input, consider the runtime regex, which selects a linear-time engine when possible.

Returns

StaticRegex object for faster matching.

Parameters

Name	Description
pattern	Regular expression
flags	The attributes (g, i, m, s and x accepted)

Authors

API and utility constructs are modeled after the original std.regex by Walter Bright and Andrei Alexandrescu.
