Variants

Get

Response to a KeyValueOperation::Get, returning the value stored under the key, which may be empty

Fields

value: Value

Set

Response to a KeyValueOperation::Set, returning the value that was previously stored under the key, may be empty

Fields

previous: Value

Delete

Response to a KeyValueOperation::Delete, returning the value that was previously stored under the key, may be empty

Fields

previous: Value

Exists

Response to a KeyValueOperation::Exists, returning whether the key is present in the store

Fields

is_present: bool

ListKeys

Response to a KeyValueOperation::ListKeys, returning a list of keys that start with the prefix, and a cursor to continue listing if there are more keys

Note: the cursor is 0 if there are no more keys

Fields

keys: Vec<String>

next_cursor: u64

The cursor to continue listing keys, or 0 if there are no more keys. If the cursor is not found for the specified prefix, the response should instead include a KeyValueError::CursorNotFound error.

Trait Implementations

impl Clone for KeyValueResponse

fn clone(&self) -> KeyValueResponse

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeyValueResponse

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for KeyValueResponse

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for KeyValueResponse

fn eq(&self, other: &KeyValueResponse) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for KeyValueResponse

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for KeyValueResponse
