Function regex_syntax::is_meta_character
[−]
[src]
pub fn is_meta_character(c: char) -> bool
Returns true if the give character has significance in a regex.
These are the only characters that are allowed to be escaped, with one
exception: an ASCII space character may be escaped when extended mode (with
the x
flag) is enabld. In particular, is_meta_character(' ')
returns
false
.
Note that the set of characters for which this function returns true
or
false
is fixed and won't change in a semver compatible release.
