Struct r_extcap::DltsStep

pub struct DltsStep<'a> {
    pub interface: &'a str,
}

In the DLTs step, Wireshark asks the extcap program for the DLT for each interface. DLT stands for data link type, and is used to determine how Wireshark analyzes (dissects) the given packets.

Despite this step being named with plurals (DLTs) by extcap, only one DLT is expected for each interface. Corresponds to the --extcap-dlts argument in extcap.

Fields

interface: &'a str

The interface to print the DLT for.

Implementations

impl<'a> DltsStep<'a>

pub fn print_dlt(&self, interface: &Interface)

Print the DLT for the given interface. If you have the list of interfaces from InterfacesStep, consider using print_from_interfaces instead.

pub fn print_from_interfaces( &self, interfaces: &[&Interface] ) -> Result<(), PrintDltError>

Finds the interface within interfaces that matches the given request and prints out its DLT. Typically interfaces will be the same list given to InterfacesStep::list_interfaces.
