Function regwcomp

pub fn regwcomp(reg: &WideStr, flags: RegcompFlags) -> Result<Regex>

Compiles a regex that is in the form of a WideStr.

This is a thin wrapper around Regex::new_wide.

Arguments

• reg: regular expression to compile, as a WideStr.
• 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, regwcomp, regwexec};
use widestring::widestr;

let regcomp_flags = RegcompFlags::new().add(RegcompFlags::EXTENDED);
let regexec_flags = RegexecFlags::new().add(RegexecFlags::NONE);

let compiled_reg = regwcomp(widestr!("[[:digit:]]*"), regcomp_flags)?;
let matches = regwexec(&compiled_reg, widestr!("01234567890"), 1, regexec_flags)?;

for (i, matched) in matches.into_iter().enumerate() {
    match matched {
        Some(substr) => println!("Match {i}: '{}'", substr.display()),
        None => println!("Match {i}: <None>"),
    }
}
