Crate fast_glob

fast-glob is a high-performance glob matching crate for Rust, originally forked from devongovett/glob-match. This crate provides efficient glob pattern matching with support for multi-pattern matching and brace expansion.

Key Features

• Up to 60% performance improvement.
• Support for more complex and efficient brace expansion.
• Fixed matching issues with wildcard and globstar glob-match/issues#9.

Examples

Simple Match

Note that simple matching does not support brace expansion, but all other syntaxes do.

use fast_glob::glob_match;

let glob = "some/**/n*d[k-m]e?txt";
let path = "some/a/bigger/path/to/the/crazy/needle.txt";

assert!(glob_match(glob, path));

Brace Expansion

Brace expansion is supported using glob_match_with_brace, allowing for more complex matching patterns:

use fast_glob::glob_match_with_brace;

let glob = "some/**/{the,crazy}/?*.{png,txt}";
let path = "some/a/bigger/path/to/the/crazy/needle.txt";

assert!(glob_match_with_brace(glob, path));

Multi-Pattern Matching

Glob instances can handle multiple patterns efficiently:

use fast_glob::Glob;

let mut glob = Glob::default();
assert!(glob.add("*.txt"));
assert!(glob.is_match("file.txt"));

Syntax

fast-glob supports the following glob pattern syntax:

Syntax	Meaning
?	Matches any single character.
*	Matches zero or more characters, except for path separators (e.g., /).
**	Matches zero or more characters, including path separators. Must match a complete path segment (i.e., followed by a / or the end of the pattern).
[ab]	Matches one of the characters contained in the brackets. Character ranges, e.g., [a-z], are also supported. Use [!ab] or [^ab] to match any character except those contained in the brackets.
{a,b}	Matches one of the patterns contained in the braces. Any of the wildcard characters can be used in the sub-patterns. Braces may be nested up to 10 levels deep.
!	When at the start of the glob, this negates the result. Multiple ! characters negate the glob multiple times.
\	A backslash character may be used to escape any of the above special characters.
