Struct ScriptRouter 

pub struct ScriptRouter { /* private fields */ }

Script-based router powered by the rhai scripting engine.

Evaluates routing rules written in rhai script to filter invokers. The script has access to helper functions for querying invoker properties and invocation context, and must return an array of selected invoker indices.

Script API

Function	Return	Description
invoker_count()	i64	Number of invokers
invoker_ip(i)	String	IP of invoker at index i
invoker_has_param(i, key)	bool	Check URL param existence
invoker_get_param(i, key)	String	Get URL param value
method_name()	String	Current method name
has_attachment(key)	bool	Check attachment existence
get_attachment(key)	String	Get attachment value

The script must return an Array of i64 indices.

Implementations

pub fn new(script: &str) -> Result<Self, Box<EvalAltResult>>

Compile a rhai script and create a new ScriptRouter.

Errors

Returns rhai::EvalAltResult if the script fails to compile.
