Struct CtxPair

pub struct CtxPair<CC, BC> {
    pub core_ctx: CC,
    pub bindings_ctx: BC,
}

A concrete implementation of ContextPair.

CtxPair provides a ContextPair implementation when CC and BC are ContextProvider and using their respective targets as the CoreContext and BindingsContext associated types.

Fields

core_ctx: CC

The core context.

bindings_ctx: BC

The bindings context.

Implementations

impl<CC, BC> CtxPair<CC, BC>

pub fn with_core_ctx(core_ctx: CC) -> CtxPair<CC, BC>

where BC: Default,

Creates a new CtxPair with core_ctx and a default bindings context.

pub fn with_default_bindings_ctx<F>(builder: F) -> CtxPair<CC, BC>

where F: FnOnce(&mut BC) -> CC, BC: Default,

Creates a new CtxPair with a default bindings context and a core context resulting from builder.

pub fn as_mut(&mut self) -> CtxPair<&mut CC, &mut BC>

Creates a new CtxPair with a mutable borrow of the contexts.

pub fn new_with_builder( builder: <CC as BuildableCoreContext<BC>>::Builder, ) -> CtxPair<CC, BC>

where CC: BuildableCoreContext<BC>, BC: Default,

Creates a new CtxPair with a default bindings context and the provided core context builder.
