Struct AeronClaim 

pub struct AeronClaim { /* private fields */ }

Zero-copy claim on a publication’s term buffer with a RAII commit-or-abort lifecycle.

A AeronClaim that is dropped without being explicitly committed or aborted is aborted in Drop, releasing the term-buffer slot immediately instead of waiting for AERON_PUBLICATION_UNBLOCK_TIMEOUT_NS (default 15s). AeronClaim::commit / AeronClaim::abort consume self, encoding Aeron’s one-shot claim contract in the type system.

Construct via AeronPublication::try_claim_owned or AeronExclusivePublication::try_claim_owned; the claim is returned only on a successful try_claim, so its inner buffer is always a genuinely claimed slot (never a null zero-default).

Implementations

impl AeronClaim

pub fn data(&mut self) -> &mut [u8]

The writable claimed slice (zero-copy into the publication term buffer).

pub fn len(&self) -> usize

Length of the claimed slice in bytes.

pub fn is_empty(&self) -> bool

Whether the claimed slice is empty.

pub fn position(&self) -> i64

Stream position Aeron assigned to this claim.

pub fn commit(self) -> Result<i64, AeronCError>

Commit the claimed bytes, publishing them to subscribers. Consumes self.

pub fn abort(self) -> Result<(), AeronCError>

Abort the claim, discarding the slot as padding for subscribers. Consumes self.

Trait Implementations

impl Drop for AeronClaim

fn drop(&mut self)

Executes the destructor for this type.
