Trait Program

pub trait Program {
    // Required method
    fn new(params: HashMap<String, String>) -> Self;

    // Provided method
    fn run(&self) -> i32 { ... }
}
Expand description

Extend the ability of Easegress by implement Program trait.

Required Methods§

Source

fn new(params: HashMap<String, String>) -> Self

Easegress will call new when initializing the WasmHost filter. You can initialize your struct here.

The parameter is a HashMap<String, String> representing parameters field in the spec.

e.g. With this spec:

filters:
- name: wasm
  kind: WasmHost
  parameters:
    blockRatio: "0.4"
    maxPermission: "3"

HashMap<String, String> contains {“blockRation”: “0.4”, “maxPermission”: “3”}.

Provided Methods§

Source

fn run(&self) -> i32

Easegress will call run on each request.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
