Trait ConfigCenter 

pub trait ConfigCenter: Send + Sync {
    // Required methods
    fn get(&self, key: &str) -> Option<String>;
    fn set(&mut self, key: &str, value: &str);
    fn delete(&mut self, key: &str) -> bool;

Configuration center abstraction (Consul/Nacos/etc).

Required Methods

fn get(&self, key: &str) -> Option<String>

fn set(&mut self, key: &str, value: &str)

fn delete(&mut self, key: &str) -> bool

fn exists(&self, key: &str) -> bool

fn list(&self) -> Vec<String>

fn watch(&self, key: &str) -> bool

Returns true if a watch was successfully registered. In this in-memory implementation, registration always succeeds.

fn subscribe(&mut self, key: &str, callback: ConfigChangeCallback)

Registers a callback for changes to key.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
