Decoder

Struct Decoder

pub struct Decoder { /* private fields */ }

Expand description

Synchronous frame decoder. It knows no logical ranges or I/O offsets. Authentication precedes decompression. Reuse one instance and the caller’s buffer to amortize allocations. Compression may swap the buffer allocation.

Implementations§

impl Decoder

pub fn decode_frame( &mut self, spec: FrameSpec, buffer: &mut Vec<u8>, ) -> Result<()>

Replace one complete stored frame with its complete decoded bytes. On failure the buffer is cleared. No unauthenticated bytes are returned. Clearing the buffer is not a promise to zero its allocation or scratch.

Trait Implementations§

impl TryFrom<&Metadata> for Decoder

type Error = Error

The type returned in the event of a conversion error.

fn try_from(metadata: &Metadata) -> Result<Self>

Performs the conversion.

impl TryFrom<Metadata> for Decoder

type Error = Error

The type returned in the event of a conversion error.

fn try_from(metadata: Metadata) -> Result<Self>

Performs the conversion.
