Enum Payload 

pub enum Payload {
    Inline,
    Owned(Vec<u8>),
    Bytes(Bytes),
    Pooled(PooledBuf),
}

Payload storage for a frame.

Variants

Inline

Payload bytes live inside MsgDescHot::inline_payload.

Owned(Vec<u8>)

Payload bytes are owned as a heap allocation.

Bytes(Bytes)

Payload bytes are stored in a ref-counted buffer (cheap clone).

Pooled(PooledBuf)

Payload bytes backed by a buffer pool (returns to pool on drop).

Placeholder for pooled buffers (see issue #46).

Implementations

impl Payload

pub fn as_slice<'a>(&'a self, desc: &'a MsgDescHot) -> &'a [u8]

Borrow the payload as a byte slice.

pub fn external_slice(&self) -> Option<&[u8]>

Borrow the payload as a byte slice without needing a descriptor.

Returns None for Payload::Inline, since inline bytes live inside MsgDescHot.

pub fn len(&self, desc: &MsgDescHot) -> usize

Returns the payload length in bytes.

pub fn is_inline(&self) -> bool

Returns true if this payload is stored inline.

Trait Implementations

impl Debug for Payload

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

Formats the value using the given formatter.
