Struct SilkFrameHeader 

pub struct SilkFrameHeader {
    pub vad_flag: bool,
    pub lbrr_flag: bool,
    pub signal_type: u8,
    pub quantization_offset: u8,
}

Parsed header fields from a SILK frame.

Fields

vad_flag: bool

Voice activity detection flag.

lbrr_flag: bool

Low Bitrate Redundancy (LBRR) payload present.

signal_type: u8

Signal type: 0 = inactive, 1 = voiced, 2 = unvoiced.

quantization_offset: u8

Quantization offset type (0 or 1).

Implementations

impl SilkFrameHeader

pub fn parse(data: &[u8]) -> Result<Self, String>

Parses a SilkFrameHeader from the first byte(s) of a raw frame.

The SILK frame header is packed into the leading bits of the payload. This parser reads the minimum information needed to scaffold frame processing; full SILK decoding requires an entropy/range decoder.

Layout of byte 0:

Bit 7: VAD flag
Bit 6: LBRR flag
Bits 5-4: signal_type (0-2, values 0b11 treated as inactive)
Bit 3: quantization_offset
Bits 2-0: reserved / additional payload bits

Trait Implementations

impl Clone for SilkFrameHeader

fn clone(&self) -> SilkFrameHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SilkFrameHeader

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

Formats the value using the given formatter.

impl PartialEq for SilkFrameHeader

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