Implementations

impl Header

pub fn parse(data: &[u8]) -> Result<Header, Error>

Parse the header into a header structure

pub fn write(&self, data: &mut [u8])

Write a header to a buffer slice

Panics

When buffer size is not exactly 12 bytes

pub fn set_truncated(data: &mut [u8])

Set “truncated flag” in the raw data

pub fn size() -> usize

Returns a size of the header (always 12 bytes)

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl PartialEq<Header> for Header

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

This method tests for self and other values to be equal, and is used by ==.

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

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