Struct Pattern

Source
pub struct Pattern { /* private fields */ }
Expand description

A compiled Unix shell style pattern.

  • ? matches any single character.

  • * matches any (possibly empty) sequence of characters.

  • ** matches the current directory and arbitrary subdirectories. To match files in arbitrary subdiretories, use **/*.

    This sequence must form a single path component, so both **a and b** are invalid and will result in an error. A sequence of more than two consecutive * characters is also invalid.

  • [...] matches any character inside the brackets. Character sequences can also specify ranges of characters, as ordered by Unicode, so e.g. [0-9] specifies any character between 0 and 9 inclusive. An unclosed bracket is invalid.

  • [!...] is the negation of [...], i.e. it matches any characters not in the brackets.

  • The metacharacters ?, *, [, ] can be matched by using brackets (e.g. [?]). When a ] occurs immediately following [ or [! then it is interpreted as being part of, rather then ending, the character set, so ] and NOT ] can be matched by []] and [!]] respectively. The - character can be specified inside a character sequence pattern by placing it at the start or the end, e.g. [abc-].

Implementations§

Source§

impl Pattern

Source

pub fn new(pattern: &str) -> Result<Pattern, PatternError>

This function compiles Unix shell style patterns.

An invalid glob pattern will yield a PatternError.

Source

pub fn escape(s: &str) -> String

Escape metacharacters within the given string by surrounding them in brackets. The resulting string will, when compiled into a Pattern, match the input string and nothing else.

Source

pub fn matches(&self, str: &str) -> bool

Return if the given str matches this Pattern using the default match options (i.e. MatchOptions::new()).

§Examples
use glob::Pattern;

assert!(Pattern::new("c?t").unwrap().matches("cat"));
assert!(Pattern::new("k[!e]tteh").unwrap().matches("kitteh"));
assert!(Pattern::new("d*g").unwrap().matches("doog"));
Source

pub fn matches_path(&self, path: &Path) -> bool

Return if the given Path, when converted to a str, matches this Pattern using the default match options (i.e. MatchOptions::new()).

Source

pub fn matches_with(&self, str: &str, options: MatchOptions) -> bool

Return if the given str matches this Pattern using the specified match options.

Source

pub fn matches_path_with(&self, path: &Path, options: MatchOptions) -> bool

Return if the given Path, when converted to a str, matches this Pattern using the specified match options.

Source

pub fn as_str(&self) -> &str

Access the original glob pattern.
