Implementations

impl DoorBell

pub fn ring(&self) -> Result<(), Error>

Rings the doorbell to trigger the execution of previously enqueued operations.

This method uses unsafe code to directly interact with the RDMA device, sending a signal from the source pointer to the destination pointer.

Returns

• Ok(()) if the operation is successful.
• Err(anyhow::Error) if an error occurs during the operation.

Trait Implementations

impl Clone for DoorBell

fn clone(&self) -> DoorBell

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DoorBell

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DoorBell

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Named for DoorBell

fn typename() -> &'static str

The globally unique type name for the type. This should typically be the fully qualified Rust name of the type.

fn typehash() -> u64

A globally unique hash for this type. TODO: actually enforce perfect hashing

fn typeid() -> TypeId

The TypeId for this type. TypeIds are unique only within a binary, and should not be used for global identification.

fn port() -> u64

The globally unique port for this type. Typed ports are in the range of 1<<63..1<<64-1.

fn arm(&self) -> Option<&'static str>

If the named type is an enum, this returns the name of the arm of the value self.

unsafe fn arm_unchecked(self_: *const ()) -> Option<&'static str>

An unsafe version of ‘arm’, accepting a pointer to the value, for use in type-erased settings.

impl Serialize for DoorBell

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
