Struct Walk 

pub struct Walk<T: Transport> { /* private fields */ }

Async stream for walking an OID subtree using GETNEXT.

Created by Client::walk_getnext().

Implementations

impl<T> Walk<T>

where T: Transport + 'static,

pub async fn next(&mut self) -> Option<Result<VarBind>>

Get the next varbind, or None when complete.

pub async fn collect(self) -> Result<Vec<VarBind>>

Collect all remaining varbinds.

If the walk completes with no results, a fallback GET is attempted on the base OID to handle scalar objects (e.g. sysDescr.0) that a GETNEXT/GETBULK walk would step past. The result is only returned when it is a real value and the max_results cap permits it; genuine absence is swallowed and real errors are propagated.

Trait Implementations

impl<T: Transport + 'static> Stream for Walk<T>

type Item = Result<VarBind, Box<Error>>

Values yielded by the stream.

fn poll_next( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Option<Self::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.
