Function validate 

pub fn validate(glob: impl AsRef<[u8]>) -> Result<(), Error>

Checks that glob is a valid pattern.

glob_match has no way to report an invalid pattern, and its result for one is unspecified. Call this once when a pattern is first accepted (e.g. at configuration load time) to reject invalid patterns with an actionable error instead of silently matching nothing.

A pattern accepted here is never treated as invalid by glob_match, so its matching behavior is well-defined. For a rejected pattern the result of glob_match is unspecified — typically it matches nothing.

Examples

use fast_glob::{validate, Error, ErrorKind};

assert!(validate("some/**/n*d[k-m]e?txt").is_ok());
assert_eq!(
    validate("src/**/*.{js,ts"),
    Err(Error { kind: ErrorKind::UnclosedBrace, index: 9 })
);
