Struct BackendRef 

pub struct BackendRef { /* private fields */ }

BackendRef can be created from a VCL_BACKEND and will handle proper refcounting. When dropped, the refcount will be decreased. This is the type that director vmods should use when storing backend references, instead of dealing with VCL_BACKEND directly.

Implementations

impl BackendRef

pub unsafe fn new(bep: VCL_BACKEND) -> Option<Self>

Create a BackendRef from a VCL_BACKEND.

pub fn probe(&self, ctx: &Ctx<'_>) -> ProbeResult

Test the underlying backend for its health.

pub fn name(&self) -> &CStr

Return the VCL name of the underlying backend.

pub unsafe fn vcl_ptr(&self) -> VCL_BACKEND

Return the C pointer to the underlying backend.

Trait Implementations

impl<S: VclBackend<T>, T: VclResponse> AsRef<BackendRef> for Backend<S, T>

fn as_ref(&self) -> &BackendRef

Converts this type into a shared reference of the (usually inferred) input type.

impl<D: VclDirector> AsRef<BackendRef> for Director<D>

fn as_ref(&self) -> &BackendRef

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for BackendRef

fn clone(&self) -> BackendRef

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BackendRef

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for BackendRef

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl IntoVCL<VCL_BACKEND> for BackendRef

fn into_vcl(self, _: &mut Workspace<'_>) -> Result<VCL_BACKEND, VclError>
