Struct RecvMeta 

#[non_exhaustive]
pub struct RecvMeta {
    pub addr: SocketAddr,
    pub len: usize,
    pub stride: usize,
    pub ecn: Option<EcnCodepoint>,
    pub dst_ip: Option<IpAddr>,
    pub interface_index: Option<u32>,
}

Metadata for a single buffer filled with bytes received from the network

This associated buffer can contain one or more datagrams, see stride.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

addr: SocketAddr

The source address of the datagram(s) contained in the buffer

len: usize

The number of bytes the associated buffer has

stride: usize

The size of a single datagram in the associated buffer

When GRO (Generic Receive Offload) is used this indicates the size of a single datagram inside the buffer. If the buffer is larger, that is if len is greater then this value, then the individual datagrams contained have their boundaries at stride increments from the start. The last datagram could be smaller than stride.

ecn: Option<EcnCodepoint>

The Explicit Congestion Notification bits for the datagram(s) in the buffer

dst_ip: Option<IpAddr>

The destination IP address which was encoded in this datagram

Populated on platforms: Windows, Linux, Android (API level > 25), FreeBSD, OpenBSD, NetBSD, macOS, and iOS.

interface_index: Option<u32>

The interface index of the interface on which the datagram was received
