Struct Header

pub struct Header {
    pub flags: Flags,
    pub frame_num: FrameNum,
    pub data_len: u32,
}

Header of a frame.

Fields

flags: Flags

Frame flags.

frame_num: FrameNum

Frame number.

data_len: u32

Data length.

Implementations

impl Header

pub const SIZE: usize = 8usize

Size of the header in bytes.

pub const fn builder() -> Builder

Create a new Builder for Header.

pub fn to_bytes(self) -> HeaderBytes

Convert the header to its byte representation.

impl Header

pub fn try_parse(bytes: &[u8]) -> Result<Result<Self, Wants>, HeaderError>

Try to parse a header from bytes.

This method will try to parse a header from the first bytes of bytes. Returns:

• Ok(None) if bytes does not contain enough data to form a header,
• Ok(Some(header)) if a header could be successfully parsed from bytes,
• Err(...) if there was an error while parsing the header

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a duplicate 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 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.
