pub struct KeySeq { /* fields omitted */ }

Trait Implementations

impl Clone for KeySeq

fn clone(&self) -> KeySeq

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CompactSeq for KeySeq

type Item = Key

item type

fn get(&self, index: usize) -> Option<Key>

get nth element. Guaranteed to succeed with Some for index < count.

fn len(&self) -> usize

number of elements

fn estimated_size(&self) -> usize

Provide a size estimation, which is used to calculate the overall size of the node for caching purposes. This function should be overridden, if the used item type contains any heap allocated objects, otherwise the default implementation is a rough estimate.

fn first(&self) -> Self::Item

first key

fn last(&self) -> Self::Item

last key

fn to_vec(&self) -> Vec<Self::Item, Global>

utility function to get all items for a compactseq.

fn select(&self, bits: &[bool]) -> Vec<Self::Item, Global>

utility function to select some items for a compactseq.

fn count(&self) -> u64

number of elements as an u64, for convenience

fn is_empty(&self) -> bool

impl Debug for KeySeq

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

Formats the value using the given formatter.

impl Decode<DagCborCodec> for KeySeq

fn decode<R: Read + Seek>(c: DagCborCodec, r: &mut R) -> Result<Self>

Decode from an impl Read.

impl<'de> Deserialize<'de> for KeySeq

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Encode<DagCborCodec> for KeySeq

fn encode<W: Write>(&self, c: DagCborCodec, w: &mut W) -> Result<()>

Encodes into a impl Write.

impl FromIterator<Key> for KeySeq

fn from_iter<T: IntoIterator<Item = Key>>(iter: T) -> Self

Creates a value from an iterator.

impl Serialize for KeySeq

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl Summarizable<Key> for KeySeq

fn summarize(&self) -> Key
