Struct Regex 

pub struct Regex { /* private fields */ }

A compiled pattern.

Compiling allocates and matching does not, which is the split ARGREP wants: a pattern is compiled once when the command is parsed and then run against every element the range touches.

Implementations

impl Regex

pub fn new(pattern: &[u8], nocase: bool) -> Result<Regex, Error>

Compile pattern as an extended regular expression over bytes.

nocase is REG_ICASE, and it is applied while the byte classes are built rather than while matching, so it costs nothing per element.

Errors

Any of Error, carrying TRE’s own message for the same mistake.

Trait Implementations

impl Debug for Regex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
