Struct td_rredis::Script

pub struct Script { /* private fields */ }

Represents a lua script.

Implementations

impl Script

The script object represents a lua script that can be executed on the redis server. The object itself takes care of automatic uploading and execution. The script object itself can be shared and is immutable.

Example:

let script = td_rredis::Script::new(r"
    return tonumber(ARGV[1]) + tonumber(ARGV[2]);
");
let result = script.arg(1).arg(2).invoke(&con);
assert_eq!(result, Ok(3));

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

Creates a new script object.

pub fn new_hash(hash: &str) -> Script

pub fn new_path_hash(path: &str, hash: &str) -> RedisResult<Script>

pub fn get_hash(&self) -> &str

Returns the script’s SHA1 hash in hexadecimal format.

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

Creates a script invocation object with a key filled in.

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

Creates a script invocation object with an argument filled in.

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

Returns an empty script invocation object. This is primarily useful for programmatically adding arguments and keys because the type will not change. Normally you can use arg and key directly.

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

Invokes the script directly without arguments.
