Trait fvm::kernel::Context

pub trait Context {
    type WithContext;

    fn context<D>(self, context: D) -> Self::WithContext
    where
        D: Display;
    fn with_context<D, F>(self, cfn: F) -> Self::WithContext
    where
        D: Display,
        F: FnOnce() -> D;
}

The FVM’s equivalent of anyhow::Context. This is intentionally only implemented on ExecutionError and Result<T, ExecutionError> so anyhow::Context can be imported at the same time.
