Struct CryptoFrame

pub struct CryptoFrame { /* private fields */ }

CRYPTO Frame

CRYPTO Frame {
  Type (i) = 0x06,
  Offset (i),
  Length (i),
  Crypto Data (..),
}

See crypto frames of QUIC for more details.

Implementations

impl CryptoFrame

pub fn new(offset: VarInt, length: VarInt) -> Self

Create a new CryptoFrame with the given offset and length.

pub fn offset(&self) -> u64

Return the offset of the frame.

pub fn length(&self) -> u64

Return the length of the frame.

pub fn estimate_max_capacity(capacity: usize, offset: u64) -> Option<usize>

Evaluate the maximum number of bytes of data that can be accommodated, starting from a certain offset, within a given capacity. If it cannot accommodate a CryptoFrame header or can only accommodate 0 bytes, return None.

Note: Panic if the offset exceeds 2^62-1, or the the capacity is too large (about 2^32. It is impossible to have so much crypto stream data)

pub fn range(&self) -> Range<u64>

Return the range of bytes that this frame covers.

Trait Implementations

impl Clone for CryptoFrame

fn clone(&self) -> CryptoFrame

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CryptoFrame

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

Formats the value using the given formatter.

impl EncodeSize for CryptoFrame

fn max_encoding_size(&self) -> usize

Return the max number of bytes needed to encode this value

fn encoding_size(&self) -> usize

Return the exact number of bytes needed to encode this value

impl GetFrameType for CryptoFrame

fn frame_type(&self) -> FrameType

Return the type of frame

impl PartialEq for CryptoFrame

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