Struct BufferMut 

pub struct BufferMut { /* private fields */ }

Mutable append-only builder used while bytes are still arriving. When the ingest stream terminates, call BufferMut::freeze to convert into an immutable ZeroCopyBuffer with a single Arc construction (no copy).

Implementations

impl BufferMut

pub fn with_capacity(capacity: usize, kind: BufferKind) -> Self

Build with initial reserved capacity.

pub fn with_tenant(self, tenant_id: impl Into<Arc<str>>) -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn capacity(&self) -> usize

pub fn extend_from_slice(&mut self, bytes: &[u8])

Append bytes. Grows the internal Vec using the standard doubling policy.

pub fn freeze(self) -> ZeroCopyBuffer

Freeze into an immutable ZeroCopyBuffer. This is the moment the storage transitions from Vec<u8> (unique mutable) to Arc<[u8]> (shared immutable). The Vec -> Arc<[u8]> conversion reuses the allocation when possible.

Trait Implementations

impl Debug for BufferMut

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

Formats the value using the given formatter.
