Crate fast_glob

Expand description

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:

SyntaxMeaning
?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.

For detailed usage and API reference, refer to the specific function and struct documentation.
