Struct FetchObjectMeta 

pub struct FetchObjectMeta {
    pub group_id: u64,
    pub subgroup_id: u64,
    pub object_id: u64,
    pub publisher_priority: u8,
    pub extension_headers_len: u64,
    pub payload_length: u64,
    pub status: Option<u64>,
    pub wire_len: u64,
}

The framing of one fetch object, without its payload.

Produced by FetchObject::decode_meta for callers that forward an object’s bytes verbatim and never inspect the payload.

Fields

group_id: u64

Group ID.

subgroup_id: u64

Subgroup ID.

object_id: u64

Object ID.

publisher_priority: u8

Publisher priority.

extension_headers_len: u64

Byte length of the extension-header block’s contents, excluding its length prefix.

payload_length: u64

Declared payload length. Zero when status is Some.

status: Option<u64>

Object Status wire code, present only when the payload is empty.

wire_len: u64

Total bytes this object occupies on the wire, prefix fields included.

Implementations

impl FetchObjectMeta

pub fn payload_permission(&self) -> Option<PayloadPermission>

Whether this object’s status permits it a non-empty payload.

The fetch-stream twin of SubgroupObjectMeta::payload_permission, and it answers on the same terms: None for a code this draft does not assign, and PayloadPermission::Permitted for an absent status, which a meta has only when its payload length is non-zero.
