Struct RequestIdAllocator 

pub struct RequestIdAllocator {
    next_id: u64,
    max_id: u64,
}

Allocates and validates request IDs per the MoQT draft-12 spec.

Draft-12 uses the same monotonic allocation rules as draft-11. The subscriber allocates IDs monotonically starting at 0; SUBSCRIBE, FETCH, PUBLISH, ANNOUNCE, etc. all share the same namespace since each carries a request_id field.

Fields

next_id: u64

max_id: u64

Implementations

impl RequestIdAllocator

pub fn new() -> Self

Create a new allocator starting at request_id 0 with max_id = 0 (blocked until the peer sends MAX_REQUEST_ID).

pub fn allocate(&mut self) -> Result<VarInt, RequestIdError>

Allocate the next request ID.

pub fn update_max(&mut self, new_max: u64) -> Result<(), RequestIdError>

Update the maximum allowed request ID (can only increase).

pub fn validate_peer_id(&self, id: u64) -> Result<(), RequestIdError>

Validate a request ID received from the peer.

pub fn is_blocked(&self) -> bool

Check if we are blocked (max_id is 0 or next_id >= max_id).

pub fn max_id(&self) -> u64

Get the current maximum request ID.

Trait Implementations

impl Default for RequestIdAllocator

fn default() -> Self

Returns the “default value” for a type.
