Expand description
A type describing the different flavors of .
.
This type is meant to be used with Hir::dot
, which is a convenience
routine for building HIR values derived from the .
regex.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
AnyChar
Matches the UTF-8 encoding of any Unicode scalar value.
This is equivalent to (?su:.)
and also \p{any}
.
AnyByte
Matches any byte value.
This is equivalent to (?s-u:.)
and also (?-u:[\x00-\xFF])
.
AnyCharExcept(char)
Matches the UTF-8 encoding of any Unicode scalar value except for the
char
given.
This is equivalent to using (?u-s:.)
with the line terminator set
to a particular ASCII byte. (Because of peculiarities in the regex
engines, a line terminator must be a single byte. It follows that when
UTF-8 mode is enabled, this single byte must also be a Unicode scalar
value. That is, ti must be ASCII.)
(This and AnyCharExceptLF
both exist because of legacy reasons.
AnyCharExceptLF
will be dropped in the next breaking change release.)
AnyCharExceptLF
Matches the UTF-8 encoding of any Unicode scalar value except for \n
.
This is equivalent to (?u-s:.)
and also [\p{any}--\n]
.
AnyCharExceptCRLF
Matches the UTF-8 encoding of any Unicode scalar value except for \r
and \n
.
This is equivalent to (?uR-s:.)
and also [\p{any}--\r\n]
.
AnyByteExcept(u8)
Matches any byte value except for the u8
given.
This is equivalent to using (?-us:.)
with the line terminator set
to a particular ASCII byte. (Because of peculiarities in the regex
engines, a line terminator must be a single byte. It follows that when
UTF-8 mode is enabled, this single byte must also be a Unicode scalar
value. That is, ti must be ASCII.)
(This and AnyByteExceptLF
both exist because of legacy reasons.
AnyByteExceptLF
will be dropped in the next breaking change release.)
AnyByteExceptLF
Matches any byte value except for \n
.
This is equivalent to (?-su:.)
and also (?-u:[[\x00-\xFF]--\n])
.
AnyByteExceptCRLF
Matches any byte value except for \r
and \n
.
This is equivalent to (?R-su:.)
and also (?-u:[[\x00-\xFF]--\r\n])
.
