Trait ReplaceContext

pub trait ReplaceContext<C: Context>: View {
    type Target: View<Context = C>;

    // Required method
    async fn with_context(
        &mut self,
        ctx: impl FnOnce(&Self::Context) -> C + Clone,
    ) -> Self::Target;
}

A view which can have its context replaced.

Required Associated Types

type Target: View<Context = C>

The type returned after replacing the context.

Required Methods

async fn with_context( &mut self, ctx: impl FnOnce(&Self::Context) -> C + Clone, ) -> Self::Target

Returns a view with a replaced context.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
