Struct smoltcp::phy::PcapWriter

pub struct PcapWriter<D, S>where
    D: for<'a> Device<'a>,
    S: PcapSink + Clone,{ /* private fields */ }

A packet capture writer device.

Every packet transmitted or received through this device is timestamped and written (in the libpcap format) using the provided sink. Note that writes are fine-grained, and buffering is recommended.

The packet sink should be cheaply cloneable, as it is cloned on every transmitted packet. For example, &'a mut Vec<u8> is cheaply cloneable but &std::io::File
