An Interface Description Block (IDB) is the container for information describing an interface on which packet data is captured.

Fields

block_type: u32

block_len1: u32

linktype: Linktype

reserved: u16

snaplen: u32

options: Vec<PcapNGOption<'a>>

block_len2: u32

if_tsresol: u8

if_tsoffset: i64

Implementations

impl<'a> InterfaceDescriptionBlock<'a>

pub fn ts_resolution(&self) -> Option<u64>

Decode the interface time resolution, in units per second

Return the resolution, or None if the resolution is invalid (for ex. greater than 2^64)

pub fn ts_offset(&self) -> i64

Return the interface timestamp offset

Trait Implementations

impl<'a> Debug for InterfaceDescriptionBlock<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> ToVec for InterfaceDescriptionBlock<'a>

Available on crate feature serialize only.

fn fix(&mut self)

Check and correct all fields: use magic, set time resolution and fix lengths fields

fn to_vec_raw(&self) -> Result<Vec<u8>, GenError>

Serialize to bytes representation. Do not check values

fn to_vec(&mut self) -> Result<Vec<u8>, GenError>

Serialize to bytes representation (little-endian). Check values and fix all fields before serializing.
