Available on crate feature script only.

Represents a prepared script call.

Implementations

impl<'a> ScriptInvocation<'a>

This type collects keys and other arguments for the script so that it can be then invoked. While the Script type itself holds the script, the ScriptInvocation holds the arguments that should be invoked until it’s sent to the server.

pub fn arg<'b, T: ToRedisArgs>( &'b mut self, arg: T ) -> &'b mut ScriptInvocation<'a>

where 'a: 'b,

Adds a regular argument to the invocation. This ends up as ARGV[i] in the script.

pub fn key<'b, T: ToRedisArgs>( &'b mut self, key: T ) -> &'b mut ScriptInvocation<'a>

where 'a: 'b,

Adds a key argument to the invocation. This ends up as KEYS[i] in the script.

pub fn invoke<T: FromRedisValue>( &self, con: &mut dyn ConnectionLike ) -> RedisResult<T>

Invokes the script and returns the result.

pub async fn invoke_async<C, T>(&self, con: &mut C) -> RedisResult<T>

where C: ConnectionLike, T: FromRedisValue,

Asynchronously invokes the script and returns the result.

pub fn load(&self, con: &mut dyn ConnectionLike) -> RedisResult<String>

Loads the script and returns the SHA1 of it.

pub async fn load_async<C>(&self, con: &mut C) -> RedisResult<String>

where C: ConnectionLike,

Asynchronously loads the script and returns the SHA1 of it.
