Struct Header

pub struct Header {
    pub major: u16,
    pub minor: u16,
    pub this_zone: i32,
    pub sigfigs: u32,
    pub snaplen: u32,
    pub network: LinkType,
    pub nano_sec: bool,
    pub endianness: Endianness,
}

Header of the pcap file.

The type of frame contained in the records is described by the field network.

Fields

major: u16

Major version of this file format.

minor: u16

Minor version of this file format.

this_zone: i32

The correction time in seconds between GMT (UTC) and the local timezone of the following packet header timestamps.

Examples: If the timestamps are in GMT (UTC), this_zone is simply 0. If the timestamps are in Central European time (Amsterdam, Berlin, …) which is GMT + 1:00, this_zone must be -3600. In practice, time stamps are always in GMT, so this_zone is always 0.

sigfigs: u32

In theory, the accuracy of time stamps in the capture; in practice, all tools set it to 0.

snaplen: u32

Maximum length of a captured packet. If the initial packet is bigger than this value it will be truncated.

network: LinkType

nano_sec: bool

endianness: Endianness

Trait Implementations

impl Debug for Header

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

Formats the value using the given formatter.

impl PartialEq for Header

fn eq(&self, other: &Header) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
