Trait PrepareStep 

pub trait PrepareStep: Send + Sync {
    // Required method
    fn prepare_step<'a>(
        &'a self,
        ctx: PrepareStepContext<'a>,
    ) -> BoxFuture<'a, Result<StepOverrides, Error>>;
}

Computes overrides before each step.

Implemented for every Fn(&PrepareStepContext<'_>) -> StepOverrides closure; implement the trait directly when the decision is asynchronous.

Required Methods

fn prepare_step<'a>( &'a self, ctx: PrepareStepContext<'a>, ) -> BoxFuture<'a, Result<StepOverrides, Error>>

Returns the overrides for the step described by ctx.

Dyn Compatibility

This trait is dyn compatible.

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