pcap

Added

• Binding for pcap_dispatch added. It can be accessed via the dispatch call on Activated captures and processes a batch of packets per call, making packet loss less likely in high traffic situations.

Changed

• MSRV is now 1.64.
• Binding for pcap_breakloop added. It can be accessed via the breakloop_handle call on Activated captures.

Added

• Added packet_header_size() for applications that need to know the size of internal type pcap_pkthdr (for instance to calculate exact send queue sizes).

Added

• Added an implementation of AsFd on Capture<Active> on non-Windows.

Added

• Add want_pktap on Capture<Inactive> for Mac OS.

Changed

• Rust Edition is now 2021.
• MSRV is now 1.63.0.

Added

• Binding for pcap_loop added. It can be accessed via the for_each call on Activated captures.

Added

• capture-stream support added for Windows.

Added

• lending-iter UNSTABLE feature that introduces lending iterator using GATs.

Changed

• Examples in the docs have been fixed.

Changed

• Public API declared stable.

Added

• SendQueue::queue_sg() can add scattered packets, as a slice of std::io::IoSlices, to SendQueues.

Changed

• Rename sendqueue::Sync to sendqueue::SendSync to avoid collision with Sync in std's prelude.
• Build script will fall back to pkg-config if available and LIBPCAP_LIBDIR hasn't been explicitly set.

Changed

• MSRV is now 1.46.0.

Added

• doc will now include all features.
• Support for sendqueues on Windows.
• PacketStream::capture_mut to still be able to inject packets when using PacketStream.
• Capture::iter() that return an iterator that use a codec like Capture::stream().
• Packet<Dead>::dead_with_precision to enable creating a pcap with nanosecond precision.
• flags field to Device.

Removed

• BpfProgram no longer have Clone implementation see #261

Changed

• MSRV is now 1.41.0.
• PacketStream has been moved from mod stream to the root of the crate.
• PacketCodec has been moved from mod stream to the root of the crate.
• PacketCodec::decode() no longer returns a Result.
• PacketCodec::Type has been renamed to PacketCodec::Item.
• Device::lookup now returns Result<Option<Device>, Error> rather than Result<Device, Error>. Ok(None) means that the lookup succeeded, but no suitable devices were available. This is consistent with libpcap.
• Capture and Savefile no longer implement the Sync trait. The underlying libpcap library does not promise thread-safe access for the same capture object from multiple threads.
• Switched from winapi to windows-sys for Windows builds. windows-sys requires rustc 1.46.0.
• Capture::next have been rename next_packet to avoid any confusion with Iterator::next.

Removed

• mod stream is no longer public.
• docs-rs feature.
• full feature.
• stream::SelectableFd and stream::PacketStream::new as they were only meant to be used internally.

Changed

• capture-stream requires rustc version 1.49.0 due to dependency on tokio.

Added

• Support for device addresses.

Added

• savefile.flush support.

Changed

• Updated dependency tokio from version 0.2 to 1.0.
• capture-stream requires rustc version 1.45.0 due to dependency on tokio.

Changed

• Fix docs.rs build.

Added

• Derive(Clone) to Device struct (#100).
• Build-time libpcap version detection.
• Support for immediate mode.
• Const value for Linktype (#145).
• Support for BPF compile.

Changed

• Opt into Rust 2018.
• Now minimum supported rustc version is 1.40.0.
• Updated dependency from deprecated tokio-core to tokio 0.2.
• Updated dependency futures from version 0.1 to 0.3.
• Feature tokio renamed to capture-stream because Cargo does not allow features and dependencies to have the same name.
• PCAP_LIBDIR renamed to LIBPCAP_LIBDIR to distinguish the pcap crate from the libpcap library.
• All methods that construct objects out of a RawFd are now unsafe.
• All methods that take a raw pointer are now unsafe. Some of these functions were renamed from new to from_handle to underline this.

Removed

• Feature flags pcap-savefile-append, pcap-fopen-offline-precision (replaced by build-time libpcap version detection).
