Trait Evaluator 

pub trait Evaluator<Player, State, Trigger> {
    // Required method
    fn evaluate(
        &self,
        ctx: &AchievementContext<'_, Player, State, Trigger>,
    ) -> impl Into<EvalResult>;
}

Trait for statically typed achievement evaluators.

This is the primary abstraction for writing custom logic to evaluate whether an achievement should be awarded.

Required Methods

fn evaluate( &self, ctx: &AchievementContext<'_, Player, State, Trigger>, ) -> impl Into<EvalResult>

Evaluate the achievement for the given context.

Dyn Compatibility

This trait is not dyn compatible.

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