Trait Implementations§

source§

impl<'a, K> AsyncKeyValue for Namespaced<'a, K>
where K: AsyncKeyValue,

source§

fn execute_key_operation<'life0, 'async_trait>( &'life0 self, op: KeyOperation ) -> Pin<Box<dyn Future<Output = Result<Output, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Namespaced<'a, K>: 'async_trait,

Executes a single KeyOperation.
source§

fn key_namespace(&self) -> Option<&str>

The current namespace.
source§

fn with_key_namespace( &self, namespace: &str ) -> Namespaced<'_, Namespaced<'a, K>>
where Namespaced<'a, K>: Sized,

Access this Key-Value store within a namespace. When using the returned Namespaced instance, all keys specified will be separated into their own storage designated by namespace.
source§

fn set_key<S, V, 'a>( &'a self, key: S, value: &'a V ) -> AsyncBuilder<'a, Self, V>
where S: Into<String>, V: Serialize + Send + Sync,

Sets key to value. This function returns a builder that is also a Future. Awaiting the builder will execute Command::Set with the options given.
source§

fn set_binary_key<S, 'a>( &'a self, key: S, bytes: &'a [u8] ) -> AsyncBuilder<'a, Self, ()>
where S: Into<String>,

Sets key to bytes. This function returns a builder that is also a Future. Awaiting the builder will execute Command::Set with the options given.
source§

fn set_numeric_key<S, V>(&self, key: S, value: V) -> AsyncBuilder<'_, Self, ()>
where S: Into<String>, V: Into<Numeric>,

Sets key to value. This stores the value as a Numeric, enabling atomic math operations to be performed on this key. This function returns a builder that is also a Future. Awaiting the builder will execute Command::Set with the options given.
source§

fn increment_key_by<S, V>(&self, key: S, value: V) -> AsyncBuilder<'_, Self, V>

Increments key by value. The value stored must be a Numeric, otherwise an error will be returned. The result of the increment will be the value’s type. For example, if the stored value is currently a u64, but value is a f64, the current value will be converted to an f64, and the stored value will be an f64.
source§

fn decrement_key_by<S, V>(&self, key: S, value: V) -> AsyncBuilder<'_, Self, V>

Decrements key by value. The value stored must be a Numeric, otherwise an error will be returned. The result of the decrement will be the value’s type. For example, if the stored value is currently a u64, but value is a f64, the current value will be converted to an f64, and the stored value will be an f64.
source§

fn get_key<S>(&self, key: S) -> AsyncBuilder<'_, Self>
where S: Into<String>,

Gets the value stored at key. This function returns a builder that is also a Future. Awaiting the builder will execute Command::Get with the options given.
source§

fn delete_key<'life0, 'async_trait, S>( &'life0 self, key: S ) -> Pin<Box<dyn Future<Output = Result<KeyStatus, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, S: 'async_trait + Into<String> + Send, Self: 'async_trait,

Deletes the value stored at key.
source§

impl<'a, K> KeyValue for Namespaced<'a, K>
where K: KeyValue,

source§

fn execute_key_operation(&self, op: KeyOperation) -> Result<Output, Error>

source§

fn key_namespace(&self) -> Option<&str>

The current namespace.
source§

fn with_key_namespace( &self, namespace: &str ) -> Namespaced<'_, Namespaced<'a, K>>
where Namespaced<'a, K>: Sized,

Access this Key-Value store within a namespace. When using the returned Namespaced instance, all keys specified will be separated into their own storage designated by namespace.
source§

fn set_key<S, V, 'a>(&'a self, key: S, value: &'a V) -> Builder<'a, Self, V>
where S: Into<String>, V: Serialize + Send + Sync,

Sets key to value. This function returns a builder that is also a Future. Awaiting the builder will execute Command::Set with the options given.
source§

fn set_binary_key<S, 'a>( &'a self, key: S, bytes: &'a [u8] ) -> Builder<'a, Self, ()>
where S: Into<String>,

Sets key to bytes. This function returns a builder that is also a Future. Awaiting the builder will execute Command::Set with the options given.
source§

fn set_numeric_key<S, V>(&self, key: S, value: V) -> Builder<'_, Self, ()>
where S: Into<String>, V: Into<Numeric>,

Sets key to value. This stores the value as a Numeric, enabling atomic math operations to be performed on this key. This function returns a builder that is also a Future. Awaiting the builder will execute Command::Set with the options given.
source§

fn increment_key_by<S, V>(&self, key: S, value: V) -> Builder<'_, Self, V>

Increments key by value. The value stored must be a Numeric, otherwise an error will be returned. The result of the increment will be the value’s type. For example, if the stored value is currently a u64, but value is a f64, the current value will be converted to an f64, and the stored value will be an f64.
source§

fn decrement_key_by<S, V>(&self, key: S, value: V) -> Builder<'_, Self, V>

source§

fn delete_key<S>(&self, key: S) -> Result<KeyStatus, Error>
where S: Into<String> + Send,

Deletes the value stored at key.
