Struct `Capture`

pub struct Capture { pub index: u32, pub name: Option<Box<str>>, pub sub: Box<Hir> }

The high-level intermediate representation for a capturing group.

A capturing group always has an index and a child expression. It may also have a name associated with it (e.g., (?P<foo>\w)), but it's not necessary.

Note that there is no explicit representation of a non-capturing group in a Hir. Instead, non-capturing grouping is handled automatically by the recursive structure of the Hir itself.

Fields

index: u32: The capture index of the capture.
name: Option<Box<str>>: The name of the capture, if it exists.
sub: Box<Hir>: The expression inside the capturing group, which may be empty.
