Enum TagList 

pub enum TagList {}

A tag list is a map from tag names to their values.

To be memory efficient it is stored as a slice of key value pairs. Keys and Values are separated using a NUL and the slice is terminated with a double NUL.

Implementations

impl TagList

pub fn get<'a>(&'a self, key: &str) -> Option<&'a str>

Lookup a key’s value

pub fn is_empty(&self) -> bool

Are there any tags at all?

pub fn as_bytes(&self) -> &[u8]

Get the raw underlying memory as slice.

See TagList for a description of this memory’s layout.

This method is also exposed via an [AsRef<[u8]>] implementation.

Trait Implementations

impl AsMut<Item> for TagList

fn as_mut(&mut self) -> &mut Item

Cast to an [crate :: item :: Item] reference

impl AsRef<[u8]> for TagList

fn as_ref(&self) -> &[u8]

See TagList for a description of this memory’s layout.

impl AsRef<Item> for TagList

fn as_ref(&self) -> &Item

Cast to an [crate :: item :: Item] reference

impl Debug for TagList

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

Formats the value using the given formatter.

impl From<&TagList> for OwnedTagList

fn from(tag_list: &TagList) -> Self

Copy a TagList’s memory into an owned Vec

impl<'a> IntoIterator for &'a TagList

type Item = (&'a str, &'a str)

The type of the elements being iterated over.

type IntoIter = TagIterator<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
