Implementations

impl PcapFileHeader

pub fn read<R: Read>(reader: &mut R) -> Result<Self, PcapParseError>

Reads the file header from the reader

pub fn write<W: Write>(&self, writer: &mut W) -> Result<(), Error>

Writes the file header to the writer

Trait Implementations

impl Clone for PcapFileHeader

fn clone(&self) -> PcapFileHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PcapFileHeader

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

Formats the value using the given formatter.

impl Default for PcapFileHeader

fn default() -> Self

Returns the “default value” for a type.

impl<'a> From<&'a PcapFileHeader> for [u8; 24]

fn from(value: &'a PcapFileHeader) -> Self

Converts to this type from the input type.

impl From<PcapFileHeader> for [u8; 24]

fn from(value: PcapFileHeader) -> Self

Converts to this type from the input type.

impl PartialEq for PcapFileHeader

fn eq(&self, other: &PcapFileHeader) -> 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.

impl TryFrom<&[u8; 24]> for PcapFileHeader

type Error = PcapParseError

The type returned in the event of a conversion error.

fn try_from(bytes: &[u8; 24]) -> Result<Self, Self::Error>

Performs the conversion.
