Struct LabelRef

pub struct LabelRef<L>(pub L, pub i32);

A reference to a label plus an offset.

Tuple Fields

0: L

1: i32

Implementations

impl<L> LabelRef<L>

pub fn map<F, M>(self, f: F) -> LabelRef<M>

where F: FnMut(L) -> M,

Applies the given mapping function to the label within the label reference.

Trait Implementations

impl<L: Clone> Clone for LabelRef<L>

fn clone(&self) -> LabelRef<L>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<L: Debug> Debug for LabelRef<L>

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

Formats the value using the given formatter.

impl<L: Hash> Hash for LabelRef<L>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<L: PartialEq> PartialEq for LabelRef<L>

fn eq(&self, other: &LabelRef<L>) -> 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.
