Struct regex::CaptureNames

pub struct CaptureNames<'r>(_);
Documentation

An iterator over the names of all possible captures.

None indicates an unnamed capture; the first element (capture 0, the whole matched region) is always unnamed.

'r is the lifetime of the compiled regular expression.

Blanket Implementations

impl<T> Any for T
where
    T: 'static + ?Sized,
fn type_id(&Self) -> TypeId
impl<T> Borrow<T> for T
where
    T: ?Sized,
fn borrow(&Self) -> &T

fn borrow_mut(&mut Self) -> &mut T
impl<T> From<T> for T
fn from(t: T) -> T

Returns the argument unchanged.

where
    U: From<T>,
fn into(Self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.
