Trait Implementations

impl<F: Clone + Family, S: Clone + Update> Clone for Operation<F, S>

where S::Key: Clone, S::Value: Clone,

fn clone(&self) -> Operation<F, S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<F: Family, S: Update> Committable for Operation<F, S>

fn is_commit(&self) -> bool

If this operation is a commit operation.

impl<F: Debug + Family, S: Debug + Update> Debug for Operation<F, S>

where S::Key: Debug, S::Value: Debug,

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

Formats the value using the given formatter.

impl<F: Family, S: Update> Display for Operation<F, S>

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

Formats the value using the given formatter.

impl<F, K, V> EncodeSize for Operation<F, Ordered<K, VariableEncoding<V>>>

where F: Family, K: Key + EncodeSize, V: VariableValue, Ordered<K, VariableEncoding<V>>: EncodeSize,

fn encode_size(&self) -> usize

Returns the encoded size of this value (in bytes).

fn encode_inline_size(&self) -> usize

Returns the encoded size excluding bytes passed to BufsMut::push during Write::write_bufs. Used to size the working buffer for inline writes. Override alongside Write::write_bufs for types where large Bytes fields go via push; failing to do so will over-allocate.

impl<F, K, V> EncodeSize for Operation<F, Unordered<K, VariableEncoding<V>>>

where F: Family, K: Key + EncodeSize, V: VariableValue, Unordered<K, VariableEncoding<V>>: EncodeSize,

fn encode_size(&self) -> usize

Returns the encoded size of this value (in bytes).

fn encode_inline_size(&self) -> usize

Returns the encoded size excluding bytes passed to BufsMut::push during Write::write_bufs. Used to size the working buffer for inline writes. Override alongside Write::write_bufs for types where large Bytes fields go via push; failing to do so will over-allocate.

impl<F, K, V> FixedSize for Operation<F, Ordered<K, FixedEncoding<V>>>

where F: Family, K: Array, V: FixedValue, Ordered<K, FixedEncoding<V>>: FixedSize,

const SIZE: usize

The size of the encoded value (in bytes).

impl<F, K, V> FixedSize for Operation<F, Unordered<K, FixedEncoding<V>>>

where F: Family, K: Array, V: FixedValue, Unordered<K, FixedEncoding<V>>: FixedSize,

const SIZE: usize

The size of the encoded value (in bytes).

impl<F: Family, S: Update> Operation<F> for Operation<F, S>

type Key = <S as Update>::Key

The key type for this operation.

fn key(&self) -> Option<&Self::Key>

Returns the key if this operation involves a key, None otherwise.

fn is_update(&self) -> bool

If this operation updates its key’s value.

fn is_delete(&self) -> bool

If this operation deletes its key’s value.

fn has_floor(&self) -> Option<Location<F>>

The inactivity floor location if this operation is a commit operation with a floor value, None otherwise.

impl<F: PartialEq + Family, S: PartialEq + Update> PartialEq for Operation<F, S>

where S::Key: PartialEq, S::Value: PartialEq,

fn eq(&self, other: &Operation<F, S>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<F: Family, S: Update> Read for Operation<F, S>

where S::ValueEncoding: OperationCodec<F, S>,

type Cfg = <<S as Update>::ValueEncoding as OperationCodec<F, S>>::ReadCfg

The Cfg type parameter allows passing configuration during the read process. This is crucial for safely decoding untrusted data, for example, by providing size limits for collections or strings.

fn read_cfg(buf: &mut impl Buf, cfg: &Self::Cfg) -> Result<Self, CodecError>

Reads a value from the buffer using the provided configuration cfg.

impl<F: Family, S: Update> Write for Operation<F, S>

where S::ValueEncoding: OperationCodec<F, S>,

fn write(&self, buf: &mut impl BufMut)

Writes the binary representation of self to the provided buffer buf.

fn write_bufs(&self, buf: &mut impl BufsMut)

Writes to a BufsMut, allowing existing Bytes chunks to be appended via BufsMut::push instead of written inline. Must encode to the same format as Write::write. Defaults to Write::write.
