Struct Region

pub struct Region { /* private fields */ }

A region contains text positions for capture groups in a match result.

Implementations

impl Region

pub fn new() -> Self

pub fn pos(&self, index: usize) -> Option<(usize, usize)>

Get the start/end positions of the capture group with given index.

If there is no match for that group or the index does not correspond to a group, None is returned. The index 0 returns the whole match.

Trait Implementations

impl Clone for Region

fn clone(&self) -> Region

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Region

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

Formats the value using the given formatter.

impl Default for Region

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Region

fn eq(&self, other: &Region) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
