Enum StreamHealthProbe 

pub enum StreamHealthProbe {
    TcpConnect,
    UdpProbe {
        request: Vec<u8>,
        expect: Option<Vec<u8>>,
    },
}

A decoded L4 health probe carried on a StreamProxyConfig.

This is the runtime, proxy-local representation of the controlling StreamHealthCheck spec type (which lives in zlayer-types). The agent is responsible for translating the spec type into this enum (decoding hex escapes in the UDP request/expect payloads, etc.) before handing it to the proxy. The proxy itself never depends on zlayer-types.

Variants

TcpConnect

TCP connect probe — a successful connect() marks the backend healthy.

UdpProbe

UDP probe — send request, mark healthy iff a reply arrives. When expect is Some, the reply must additionally contain expect as a (byte) substring.

Fields

request: Vec<u8>

Raw request payload to send to the backend.

expect: Option<Vec<u8>>

Optional expected substring in the reply.

Trait Implementations

impl Clone for StreamHealthProbe

fn clone(&self) -> StreamHealthProbe

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StreamHealthProbe

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

Formats the value using the given formatter.

impl Eq for StreamHealthProbe

impl PartialEq for StreamHealthProbe

fn eq(&self, other: &StreamHealthProbe) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
