Struct StreamChunk 

#[repr(C, packed(1))]
pub struct StreamChunk {
    pub sequence: u32,
    pub flags: u8,
    pub len: u16,
}

Binary stream chunk - 7 bytes header

Fields

sequence: u32

Sequence number for ordering

flags: u8

Flags: FIRST=1, CONTINUE=2, LAST=4, ERROR=8

len: u16

Chunk payload length

Implementations

impl StreamChunk

pub const SIZE: usize = 7

Size of the chunk header in bytes

pub fn new(sequence: u32, flags: u8, len: u16) -> Self

Create a new stream chunk

pub fn first(sequence: u32, len: u16) -> Self

Create the first chunk in a stream

pub fn continuation(sequence: u32, len: u16) -> Self

Create a continuation chunk

pub fn last(sequence: u32, len: u16) -> Self

Create the last chunk in a stream

pub fn error(sequence: u32, len: u16) -> Self

Create an error chunk

pub fn from_bytes(bytes: &[u8]) -> Result<&Self, DCPError>

Parse from bytes

pub fn as_bytes(&self) -> &[u8]

Serialize to bytes

pub fn is_first(&self) -> bool

Check if this is the first chunk

pub fn is_continuation(&self) -> bool

Check if this is a continuation chunk

pub fn is_last(&self) -> bool

Check if this is the last chunk

pub fn is_error(&self) -> bool

Check if this is an error chunk

Trait Implementations

impl Clone for StreamChunk

fn clone(&self) -> StreamChunk

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for StreamChunk

impl Debug for StreamChunk

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

Formats the value using the given formatter.

impl Eq for StreamChunk

impl PartialEq for StreamChunk

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