Struct Regex

pub struct Regex<const N: usize = 1>(/* private fields */);

A regular expression (specifically, a POSIX ERE).

Internally, this may contain one of several engines depending on the expression.

The const generic N represents the number of capture groups (including capture group 0 which is the entire expression). It defaults to 1 (for just capture group 0), but you will need to specify it in the type for expressions with more capture groups.

Implementations

impl<const N: usize> Regex<N>

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

Returns whether or not the text is matched by the regular expression.

pub fn exec<'a>(&self, text: &'a str) -> Option<[Option<&'a str>; N]>

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
