Struct PhaseEncoding 

pub struct PhaseEncoding;

Phase encoding (DSSS) audio steganography adapter (STUB).

NOT YET IMPLEMENTED: Requires FFT/IFFT and phase manipulation.

TODO(T14): Implement phase encoding:

• Segment audio into blocks
• Apply FFT to each segment
• Embed one bit per segment by phase shift
• Adaptive alpha: scale shift by segment energy
• Apply IFFT to reconstruct samples
• Requires audio DSP library (rustfft or similar)

Implementations

impl PhaseEncoding

pub const fn new() -> Self

Trait Implementations

impl Debug for PhaseEncoding

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

Formats the value using the given formatter.

impl Default for PhaseEncoding

fn default() -> PhaseEncoding

Returns the “default value” for a type.

impl EmbedTechnique for PhaseEncoding

fn technique(&self) -> StegoTechnique

The technique identifier for this implementation.

fn capacity(&self, _cover: &CoverMedia) -> Result<Capacity, StegoError>
