Struct Script 

pub struct Script { /* private fields */ }

A cached Lua script with its SHA-1 hash.

Create once (computes the SHA-1), then Self::arg/Self::key to build an invocation. See the module docs for an example.

Implementations

impl Script

pub fn new(code: &str) -> Script

Create a new script object with a precomputed SHA-1 hash.

pub fn get_hash(&self) -> &str

The SHA-1 hash of the script, as used by EVALSHA.

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

Create an invocation and add a regular argument (ARGV[…]).

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

Create an invocation and add a key argument (KEYS[…]).

pub fn prepare_invoke(&self) -> ScriptInvocation<'_>

Create an empty invocation (no keys, no args).

pub async fn invoke_async<C: ScriptInvoke, T: FromValkeyValue>( &self, con: &C, ) -> ValkeyResult<T>

Invoke the script without keys or args.

pub fn invoke<C: ScriptInvokeSync, T: FromValkeyValue>( &self, con: &C, ) -> ValkeyResult<T>

Invoke the script without keys or args on a blocking connection (crate::sync::SyncGlideClient / crate::sync::SyncGlideClusterClient).

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

Load the script into the server’s script cache (SCRIPT LOAD) without running it; returns the SHA-1 hash.

pub fn load<C: Commands>(&self, con: &C) -> ValkeyResult<String>

Load the script into the server’s script cache (SCRIPT LOAD) on a blocking connection; returns the SHA-1 hash.

Trait Implementations

impl Clone for Script

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Script

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

Formats the value using the given formatter.

impl Drop for Script

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
