Implementations

impl Tags

pub fn new() -> Self

pub fn merge(a: Self, b: Self) -> Self

pub fn len(&self) -> usize

Tag count.

pub fn is_empty(&self) -> bool

No tags?

pub fn insert(&mut self, tag: Tag)

pub fn remove(&mut self, tag: &Tag)

Remove tag.

pub fn append(&mut self, tags: &mut Tags)

Insert mutiple tags.

pub fn extend(&mut self, tags: impl IntoIterator<Item = Tag>)

Insert mutiple tags.

Tags that equal exactly (key and value) will be skipped. All others will be added.

pub fn contains(&self, tag: &Tag) -> bool

Contains tag.

pub fn contains_key(&self, key: &str) -> bool

Contains tag with key.

pub fn set(&mut self, tags: impl Into<Tags>)

Set tag(s). By removing all tags with the same key before insert.

pub fn clear(&mut self, tags: Option<&Tags>) -> bool

Remove specified tags. If no tags are specified all tags will be removed. Returns true if tags has changed.

pub fn clear_key(&mut self, key: &str)

Remove tags with key. If no tags are specified all tags will be removed.

pub fn iter(&self) -> impl Iterator<Item = &Tag>

Iterate over tags.

pub fn find_key(&self, key: &str) -> Option<&Tag>

Find first tag by key.

pub fn value(&self, key: &str) -> Option<&TagValue>

Find first tag value by key.

pub fn matches<P: TagPattern>(&self, pattern: &P) -> bool

pub fn string(&self, key: &str) -> Option<&str>

Get first tag value (that is a string) for given key.

pub fn integer(&self, key: &str) -> Option<i128>

Get first tag value (that is a integer) for given key.

pub fn link(&self, key: &str) -> Option<&Cid>

Find first tag value, that is a link, by key.
