Enum ObjectStatus 

#[repr(u64)]
pub enum ObjectStatus {
    Normal = 0,
    EndOfGroup = 3,
    EndOfTrack = 4,
}

Object status values, from MoQ Transport draft-16 Section 10.2.1.1 “Object Status”.

Draft-16 is where the status set narrows to three: it assigns 0x0, 0x3 and 0x4 only. Object Does Not Exist (0x1), assigned by every draft from 07 through 15, is gone — draft-16 rewrites the section around a publisher “explicitly communicate that a specific range of objects does not exist” and drops the per-object form. Of every other value the section says: “Any other value SHOULD be treated as a protocol error and the session SHOULD be closed with a PROTOCOL_VIOLATION”. ObjectStatus::from_u64 answers None for 0x1, for 0x2, and for everything else the draft leaves unassigned.

Variants

Normal = 0

Normal object. Implicit for any non-zero length object; zero-length objects encode it explicitly.

EndOfGroup = 3

End of Group. Object ID is one greater than the largest object produced in the group identified by the Group ID; 0 means the group is empty.

EndOfTrack = 4

End of Track. Either Group ID is the largest group produced in the track and Object ID is one greater than the largest object in that group, or Group ID is one greater than the largest group produced and Object ID is zero.

Implementations

impl ObjectStatus

pub const ALL: &[ObjectStatus]

Every status draft-16 assigns, in ascending wire order.

This is exactly the set ObjectStatus::from_u64 accepts. Any other value is one the draft does not assign.

pub fn from_u64(v: u64) -> Option<Self>

Convert a raw u64 to an ObjectStatus, or None if draft-16 does not assign that value.

pub fn as_u64(self) -> u64

Return the wire value.
