Implementations

impl<Txn, FE> Collection<Txn, FE>

where Txn: Transaction<FE>, FE: CollectionBlock,

pub fn schema(&self) -> Schema

Return the Schema of this Collection.

Trait Implementations

impl<Txn, FE> AsyncHash for Collection<Txn, FE>

where Txn: Transaction<FE>, FE: CollectionBlock + Clone,

impl<Txn, FE> Clone for Collection<Txn, FE>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Txn, FE> CopyFrom<FE, Collection<Txn, FE>> for CollectionBase<Txn, FE>

where Txn: Transaction<FE>, FE: CollectionBlock,

fn copy_from<'life0, 'async_trait>( txn: &'life0 Txn, store: Dir<FE>, instance: Collection<Txn, FE>, ) -> Pin<Box<dyn Future<Output = TCResult<Self>> + Send + 'async_trait>>

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

impl<Txn, FE> Debug for Collection<Txn, FE>

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

Formats the value using the given formatter.

impl<Txn, FE> From<CollectionBase<Txn, FE>> for Collection<Txn, FE>

fn from(base: CollectionBase<Txn, FE>) -> Self

Converts to this type from the input type.

impl<T, FE> FromStream for Collection<T, FE>

where T: Transaction<FE>, FE: CollectionBlock,

type Context = T

The decoding context of this type, useful in situations where the stream to be decoded may be too large to hold in main memory.

fn from_stream<'life0, 'async_trait, D>( txn: Self::Context, decoder: &'life0 mut D, ) -> Pin<Box<dyn Future<Output = Result<Self, D::Error>> + Send + 'async_trait>>

where D: 'async_trait + Decoder, Self: 'async_trait, 'life0: 'async_trait,

Parse this value using the given Decoder.

impl<Txn, FE> Instance for Collection<Txn, FE>

where Txn: Send + Sync, FE: Send + Sync,

type Class = CollectionType

The Class type of this instance

fn class(&self) -> CollectionType

Returns the [Class] of this instance.

impl<'en, Txn, FE> IntoView<'en, FE> for Collection<Txn, FE>

where Txn: Transaction<FE>, FE: CollectionBlock,

type Txn = Txn

The type of Transaction which this state supports

type View = CollectionView<'en>

The type of encodable view returned by into_view

fn into_view<'async_trait>( self, txn: Self::Txn, ) -> Pin<Box<dyn Future<Output = TCResult<Self::View>> + Send + 'async_trait>>

where Self: 'async_trait,

Return a View which can be encoded with en::IntoStream.

impl<State> Route<State> for Collection<State::Txn, State::FE>

where State: StateInstance,

fn route<'a>( &'a self, _path: &'a [PathSegment], ) -> Option<Box<dyn Handler<'_, State> + 'a>>

impl<T, FE> TryCastFrom<Collection<T, FE>> for CollectionBase<T, FE>

fn can_cast_from(collection: &Collection<T, FE>) -> bool

Test if value can be cast into Self.

fn opt_cast_from(collection: Collection<T, FE>) -> Option<Self>

Returns Some(Self) if the source value can be cast into Self, otherwise None.

fn try_cast_from<Err, OnErr>(value: T, on_err: OnErr) -> Result<Self, Err>

where OnErr: FnOnce(&T) -> Err,

Returns Ok(Self) if the source value can be cast into Self, otherwise calls on_err.
