Errors that can occur while using the higher-level session wrapper APIs.

Variants

Socket(UdpSocketError)

UDP socket operation failed.

Packet(PacketError)

Packet view construction or parsing failed.

PayloadTooLarge

The app payload did not fit in the current Prague packet budget.

Fields

payload_len: usize

Bytes requested by the caller.

max_payload_len: usize

Maximum bytes that fit in the current datagram after Prague headers.

FrameAlreadyQueued

A video frame was queued while another one was still pending.

FrameNotReady

The next video frame slot has not opened yet.

Fields

next_frame_in_us: time_tp

Remaining delay until the next frame slot, in microseconds.

FeedbackTimeout

A blocking helper timed out while waiting for feedback needed to make progress.

Fields

waited_us: time_tp

Timeout budget used for the wait, in microseconds.

inflight_packets: count_tp

Current in-flight packet count when the timeout fired.

WouldBlock

The sender is pacing-limited or window-limited and cannot send yet.

Fields

next_send_in_us: time_tp

Remaining delay until the next pacing slot, in microseconds.

inflight_packets: count_tp

Current in-flight packet count.

packet_window: count_tp

Current packet window limit.

UnexpectedPacketType(u8)

A packet of an unexpected type was received for the current session role.

InvalidPacket(&'static str)

A packet passed structural parsing but was invalid for the higher-level wrapper.

Trait Implementations

impl Debug for SessionError

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

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
