Eclipse Symphony Target Provider Rust Binding

This crate provides the Eclipse Symphony Target provider Rust binding, which allows a custom Target provider to be written in Rust.

Symphony is a toolchain orchestrator that aims to provide consistent management experience across multiple toolchains. A key capability of Symphony is state seeking, where a system's current is brought towards a new desired state. Symphony allows different toolchains to join the state seeking process through a Target Provider trait.

pub trait ITargetProvider: Send + Sync {
    fn get_validation_rule(&self) -> Result<ValidationRule, String>;
    fn get(&self, deployment: DeploymentSpec, references: Vec<ComponentStep>) -> Result<Vec<ComponentSpec>, String>;
    fn apply(&self, deployment: DeploymentSpec, step: DeploymentStep, is_dry_run: bool) -> Result<HashMap<String, ComponentResultSpec>, String>; 
 }

• The get() method returns the current state of a system.
• The apply() method applies the new desired state.
• The get_validation_rule() allows a provider to define what properties are expected in the incoming state spec, and what properties to be used for change detection.
