Trait PacketSetFilter 

pub trait PacketSetFilter {
    // Required method
    fn set_filter(&self, filter: &BpfFilter) -> Result<(), Error>;
}

Packet sources that support atomic BPF filter replacement on a running socket (AF_PACKET semantics: setsockopt(SO_ATTACH_FILTER)).

Implemented for crate::Capture. Not implemented for AF_XDP sockets — XDP filtering happens in the XDP program, not via SO_ATTACH_FILTER.

Use via crate::Capture::set_filter directly, or via crate::AsyncCapture::set_filter (where the trait bound gates the method to AF_PACKET-backed captures only).

Required Methods

fn set_filter(&self, filter: &BpfFilter) -> Result<(), Error>

Replace the BPF filter on this source without disturbing the ring buffer or the user-space stream. The kernel handles atomic replacement of any prior filter.

To remove the filter, see implementation-specific accessors (e.g. crate::Capture::detach_filter).

Errors

Returns Error::Config if the filter is empty or oversized; Error::SockOpt if the setsockopt call fails.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
