Enum lightws::frame::length::PayloadLen

pub enum PayloadLen {
    Standard(u8),
    Extended1(u16),
    Extended2(u64),
}

Payload length.

Could be 7 bits, 7+16 bits, or 7+64 bits.

Variants

Standard(u8)

0 - 125

Extended1(u16)

126 - 65535

Extended2(u64)

over 65536

Implementations

impl PayloadLen

pub const fn from_num(n: u64) -> Self

Parse from number.

pub const fn to_num(self) -> u64

Convert to number.

pub const fn from_flag(b: u8) -> Self

Read the flag which indicates the kind of length.

If extended length is used, the caller should read the next 2 or 8 bytes to get the real length.

pub const fn to_flag(&self) -> u8

Generate the flag byte. If length <= 125, it represents the real length.

pub const fn from_byte2(buf: [u8; 2]) -> Self

Read as 16-bit length.

pub const fn from_byte8(buf: [u8; 8]) -> Self

Read as 64-bit length.

pub const fn to_u8(&self) -> u8

Get value, as 8-bit length.

pub const fn to_u16(&self) -> u16

Get value, as 16-bit length.

pub const fn to_u64(&self) -> u64

Get value, as 64-bit length.

Trait Implementations

impl Clone for PayloadLen

fn clone(&self) -> PayloadLen

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PayloadLen

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

Formats the value using the given formatter.

impl PartialEq for PayloadLen

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