Struct IpcBatch 

pub struct IpcBatch { /* private fields */ }

IPC message batch for amortizing per-message overhead.

Collects multiple small messages destined for the same target and delivers them in a single operation. This reduces per-message overhead (capability validation, task lookup) by performing these steps once per batch instead of once per message.

Implementations

impl IpcBatch

pub fn new(target_pid: u64) -> Self

Create a new empty batch targeting a specific process.

pub fn add_to_batch(&mut self, msg: SmallMessage) -> bool

Add a message to the batch.

Returns true if the batch is now full and should be flushed. Returns false if there is still room for more messages.

pub fn len(&self) -> usize

Number of messages currently in the batch.

pub fn is_empty(&self) -> bool

Whether the batch is empty.

pub fn flush(&mut self) -> usize

Flush all buffered messages by sending them via fast_send.

Each message is sent individually via the fast path. Capability validation is only performed once per batch (the first message’s capability is cached for subsequent sends).

Returns the number of messages successfully sent.

pub fn target_pid(&self) -> u64

Get the target PID for this batch.
