Struct TcpInfoProbe 

pub struct TcpInfoProbe(/* private fields */);

Captured socket handle that allows a TCP_INFO sample to be taken later, after the original TcpStream has been moved into the HTTP stack.

On Unix this holds a dup(2)’d file descriptor pointing at the same kernel socket — counters are shared. Dropping the probe closes only the duplicate; the original socket lifetime is unchanged. On non-Unix this is a zero-sized placeholder and sample() always returns None.

Implementations

impl TcpInfoProbe

pub fn capture(stream: &TcpStream) -> (Option<TcpInfo>, Option<Self>)

Take an immediate sample on the original stream (no dup needed), and return a probe that can be sampled again later.

pub fn sample(&self) -> Option<TcpInfo>

Sample the kernel TCP statistics for the held socket.
