Trait Implementations

impl AsyncNameSetQuery for SliceSet

fn iter<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<BoxVertexStream>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Iterate through the set in defined order.

fn iter_rev<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<BoxVertexStream>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Iterate through the set in the reversed order.

fn count<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<usize>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Number of names in this set.

fn contains<'life0, 'life1, 'async_trait>( &'life0 self, name: &'life1 VertexName, ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Test if this set contains a given name.

fn contains_fast<'life0, 'life1, 'async_trait>( &'life0 self, name: &'life1 VertexName, ) -> Pin<Box<dyn Future<Output = Result<Option<bool>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Test contains in less than O(N) time. Returns None if cannot achieve in less than O(N) time.

fn as_any(&self) -> &dyn Any

For downcasting.

fn hints(&self) -> &Hints

Get or set optimization hints.

fn first<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Option<VertexName>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

The first name in the set.

fn last<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Option<VertexName>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

The last name in the set.

fn is_empty<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<bool>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Test if this set is empty.

fn id_convert(&self) -> Option<&dyn IdConvert>

Get an optional IdConvert interface to check hints.

impl Clone for SliceSet

fn clone(&self) -> SliceSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SliceSet

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