Struct regex_syntax::hir::HirInfo

struct HirInfo {
    bools: u8,
}

A type that documents various attributes of an HIR expression.

These attributes are typically defined inductively on the HIR.

Fields

bools: u8

Represent yes/no questions by a bitfield to conserve space, since this is included in every HIR expression.

If more attributes need to be added, it is OK to increase the size of this as appropriate.

Trait Implementations

impl Clone for HirInfo

fn clone(&self) -> HirInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HirInfo

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

Formats the value using the given formatter.

impl Eq for HirInfo

fn assert_receiver_is_total_eq(&self)

impl PartialEq for HirInfo

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