Struct IntMap

pub struct IntMap<T> { /* private fields */ }

A mapping from a u8 to T.

Printer capabilities represented with this type will generally involve sending a key in this map as part of a command to the printer. For example, for character fonts, sending [0x1b, b'M'] followed by 0x03 to the printer selects “font D”, and correspondingly, profile.fonts.get(3) will return information about the printer’s “font D”, if it exists.

Implementations

impl<T> IntMap<T>

pub const fn empty<'a>() -> &'a Self

An empty IntMap.

pub const fn from_entries(entries: &[(u8, T)]) -> &Self

Create an IntMap from the given map entries.

Panics

This function will panic if entries is not ordered by the first field of the tuple, or has duplicates.

pub fn get(&self, k: u8) -> Option<&T>

Lookup a value by the given key.

pub fn iter(&self) -> IntMapIter<'_, T>

Returns an iterator over the entries of this map.

Trait Implementations

impl<T> AsRef<IntMap<T>> for IntMap<T>

fn as_ref(&self) -> &IntMap<T>

Converts this type into a shared reference of the (usually inferred) input type.

impl<T> Borrow<IntMap<T>> for OwnedIntMap<T>

fn borrow(&self) -> &IntMap<T>

Immutably borrows from an owned value.

impl<T: Debug> Debug for IntMap<T>

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

Formats the value using the given formatter.

impl<T> Default for &IntMap<T>

fn default() -> Self

Returns the “default value” for a type.

impl<'a, T> IntoIterator for &'a IntMap<T>

type Item = (u8, &'a T)

The type of the elements being iterated over.

type IntoIter = IntMapIter<'a, T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<T> ToOwned for IntMap<T>

type Owned = OwnedIntMap<T>

The resulting type after obtaining ownership.

fn to_owned(&self) -> Self::Owned

Creates owned data from borrowed data, usually by cloning.

fn clone_into(&self, target: &mut Self::Owned)

Uses borrowed data to replace owned data, usually by cloning.
