Trait PartialContext

pub trait PartialContext<L, R>
where
    L: From<R>,
{
    // Required methods
    fn has_context(&self) -> bool;
    fn partial(self) -> L;
    fn unwrap_context(self) -> R;
    fn context(self) -> Option<R>;

    // Provided method
    fn needs_context(&self) -> bool { ... }
}

Required Methods

fn has_context(&self) -> bool

fn partial(self) -> L

infallible since L is from R we can always fall back to L

fn unwrap_context(self) -> R

can panic if R does not have context

fn context(self) -> Option<R>

Provided Methods

fn needs_context(&self) -> bool
