Common methods for PcapNG blocks

Required Methods§

source

fn big_endian(&self) -> bool

Returns true if block is encoded as big-endian

source

fn raw_data(&self) -> &[u8] ⓘ

Raw block data (including header)

source

fn data_len(&self) -> usize

The length of inner data, if any

source

fn data(&self) -> &[u8] ⓘ

The inner data, if any

source

fn header_len(&self) -> usize

The Header length (without options)

Provided Methods§

source

fn block_type(&self) -> u32

The type of this block

source

fn block_length(&self) -> u32

The block length from the block header

source

fn block_length2(&self) -> u32

The block length from the block footer

source

fn raw_header(&self) -> &[u8] ⓘ

Raw packet header (without options)

source

fn offset_options(&self) -> usize

Return the declared offset of options. Warning: the offset can be out of bounds, caller must test value before accessing data

source

fn raw_options(&self) -> &[u8] ⓘ

Network packet options. Can be empty if packet does not contain options
