Struct SubframeHeader

pub struct SubframeHeader {
    pub type_: SubframeHeaderType,
    pub wasted_bps: u32,
}

A Subframe Header

Bits	Field	Meaning
1	pad (0)
6	type_	subframe type and (if any) order
1	has wasted bits	whether the subframe has wasted bits-per-sample
(0+)	wasted_bps	the number of wasted bits-per-sample, as unary

“Wasted” bits is when all of the samples in a given subframe have one or more 0 bits in the least-significant bits position. In this case, the samples can all be safely right shifted by that amount of wasted bits during encoding, and left shifted by that amount of bits during decoding, without loss.

This is an uncommon case.

Fields

type_: SubframeHeaderType

The subframe header’s type

wasted_bps: u32

The number of wasted bits-per-sample

Trait Implementations

impl Debug for SubframeHeader

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

Formats the value using the given formatter.

impl FromBitStream for SubframeHeader

type Error = Error

Error generated during parsing, such as io::Error

fn from_reader<R: BitRead + ?Sized>(r: &mut R) -> Result<Self, Error>

Parse Self from reader

impl ToBitStream for SubframeHeader

type Error = Error

Error generated during building, such as io::Error

fn to_writer<W: BitWrite + ?Sized>(&self, w: &mut W) -> Result<(), Error>

Generate self to writer

fn bits<C>(&self) -> Result<C, Self::Error>

where C: Counter, Self: Sized,

Returns length of self in bits, if possible

fn bits_len<C, E>(&self) -> Result<C, Self::Error>

where C: Counter, E: Endianness, Self: Sized,

👎Deprecated since 4.0.0: use of bits() is preferred

Returns total length of self, if possible
