Struct ExtraBytesBuilder 

pub struct ExtraBytesBuilder { /* private fields */ }

Mutable extra-bytes accumulator threaded through hook invocations. Hooks may append; they cannot read prior policy-invariant fields. Wraps the existing bytes::BytesMut shape so the L1 builder can adopt it without re-allocating after the hook returns.

Append a byte slice to the builder.

pub fn len(&self) -> usize

Current accumulated length.

pub fn is_empty(&self) -> bool

Empty check.

pub fn freeze(self) -> Bytes

Freeze into an immutable Bytes for downstream submission build.
