Struct redis::Script [−][src]
pub struct Script { /* fields omitted */ }
Represents a lua script.
Methods
impl Script
[src]
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 = redis::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
[src]
pub fn new(code: &str) -> Script
Creates a new script object.
pub fn get_hash(&self) -> &str
[src]
pub fn get_hash(&self) -> &str
Returns the script's SHA1 hash in hexadecimal format.
pub fn key<T: ToRedisArgs>(&self, key: T) -> ScriptInvocation
[src]
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
[src]
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
[src]
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: &ConnectionLike) -> RedisResult<T>
[src]
pub fn invoke<T: FromRedisValue>(&self, con: &ConnectionLike) -> RedisResult<T>
Invokes the script directly without arguments.
