Struct SsdpMessage 

#[non_exhaustive]
pub struct SsdpMessage {
    pub kind: SsdpKind,
    pub host: Option<String>,
    pub nt: Option<String>,
    pub nts: Option<String>,
    pub st: Option<String>,
    pub usn: Option<String>,
    pub location: Option<String>,
    pub server: Option<String>,
    pub cache_control_max_age: Option<u32>,
    pub user_agent: Option<String>,
}

Available on crate feature ssdp only.

One parsed SSDP datagram. Field semantics depend on SsdpMessage::kind.

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.

kind: SsdpKind

Whether this is an advertisement, search, or response.

host: Option<String>

HOST header — multicast address+port (e.g. "239.255.255.250:1900"). RFC 4795: required.

nt: Option<String>

NT header (NOTIFY only) — Notification Type — the device or service type being advertised.

nts: Option<String>

NTS header (NOTIFY only) — Notification Sub-Type: "ssdp:alive", "ssdp:byebye", "ssdp:update".

st: Option<String>

ST header (M-SEARCH + response) — Search Target.

usn: Option<String>

USN header — Unique Service Name. Combines a UUID with an optional :: + URN suffix.

location: Option<String>

LOCATION header — HTTP URL pointing at the device description XML.

server: Option<String>

SERVER header — vendor / firmware banner (NOTIFY + response). Operationally one of the more discriminating asset-discovery signals.

cache_control_max_age: Option<u32>

CACHE-CONTROL: max-age=<n> — TTL of the advertisement in seconds. Decoded only when the header has the exact max-age=N form.

user_agent: Option<String>

USER-AGENT header (M-SEARCH only) — the searching client’s identifier.

Implementations

impl SsdpMessage

pub fn is_byebye(&self) -> bool

Convenience: true if this is a NOTIFY with NTS: ssdp:byebye — device tearing down its announcement, often a useful “device leaving the network” signal.

pub fn is_alive(&self) -> bool

Convenience: true if this is a NOTIFY with NTS: ssdp:alive — the standard periodic re-announcement.
