Trait RegExp

pub trait RegExp: Sized {
    // Required methods
    fn syntax() -> RegexSyntax;
    fn parse(pattern: &str, flags: &str) -> Result<Self, ()>;
    fn matches<'a>(&self, text: &'a str) -> Option<Vec<Option<&'a str>>>;
}

Required Methods

fn syntax() -> RegexSyntax

fn parse(pattern: &str, flags: &str) -> Result<Self, ()>

Generates a regexp pattern for the given string. If the pattern is invalid, the parse function should return an error.

fn matches<'a>(&self, text: &'a str) -> Option<Vec<Option<&'a str>>>

Matches the given text against the regular expression and returns the list of captures. The matches are returned in the order they appear in the regular expression. It is not prefixed with the full match. For groups that occur in the regular expression, but did not match, the corresponding capture should be None.

Returns None if the text does not match the regular expression.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
