ShardQueues

Struct ShardQueues

pub struct ShardQueues { /* private fields */ }

Expand description

Sending side of every shard queue, shared by pipeline threads.

Implementations§

impl ShardQueues

pub fn num_shards(&self) -> usize

Number of shards.

pub fn capacity(&self) -> usize

Configured per-shard capacity (in chunks).

pub fn try_send( &self, shard: usize, chunk: EncodedChunk, ) -> Result<(), ChunkSendError>

Non-blocking send to shard. On Err the chunk comes back and the caller applies backpressure. A closed queue (sink shut down) also returns the chunk; the driver observes shutdown separately.

pub fn all_below(&self, ratio: f64) -> bool

Whether every shard queue is below ratio of its capacity — the resume condition the backpressure controller asks about.

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<U> As for U

fn as_<T>(self) -> T
where T: CastFrom<U>,

Casts self to type T. The semantics of numeric casting with the as operator are followed, so <T as As>::as_::<U> can be used in the same way as T as U for numeric conversions. Read more

where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> CloneToUninit for T
where T: Clone,

unsafe fn clone_to_uninit(&self, dest: *mut u8)

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