Function regcomp_bytes

pub fn regcomp_bytes(reg: &[u8], flags: RegcompFlags) -> Result<Regex>

Compiles a regex that is in the form of bytes.

This is a thin wrapper around Regex::new_bytes.

Arguments

• reg: regular expression to compile, as a string.
• flags: RegcompFlags to pass to the function.

Returns

An opaque Regex object will be returned.

Errors

Will return a RegexError upon failure.

Examples

use tre_regex::{RegcompFlags, RegexecFlags, regcomp_bytes, regexec_bytes};

let regcomp_flags = RegcompFlags::new().add(RegcompFlags::EXTENDED);
let regexec_flags = RegexecFlags::new().add(RegexecFlags::NONE);
let compiled_reg = regcomp_bytes(b"[[:digit:]]*", regcomp_flags)?;
let matches = regexec_bytes(&compiled_reg, b"01234567890", 1, regexec_flags)?;
for (i, matched) in matches.into_iter().enumerate() {
    match matched {
        Some(substr) => println!("Match {i}: '{}'",
            std::str::from_utf8(substr.as_ref()).unwrap()
        ),
        None => println!("Match {i}: <None>"),
    }
}
