Struct BinaryCodec 

pub struct BinaryCodec;

Binary codec runtime object that round-trips kernel Expr values as compact tagged frames.

As a domain codec it speaks exactly its own byte frame format: it implements every codec role – Decoder/Encoder, located LocatedDecoder/LocatedEncoder, and tree TreeDecoder/TreeEncoder – over the shared Expr graph, and fails closed (under DecodeLimits) on any input that is not a well-formed frame. Decoded bytes are treated strictly as data, never as executable input.

Trait Implementations

impl Decoder for BinaryCodec

fn decode(&self, cx: &mut ReadCx<'_>, input: Input) -> Result<Expr>

Decode input into a kernel Expr, charging the ReadCx budget.

impl Encoder for BinaryCodec

fn encode(&self, _cx: &mut WriteCx<'_>, expr: &Expr) -> Result<Output>

Encode expr into Output under the context’s encode options.

impl LocatedDecoder for BinaryCodec

fn decode_located( &self, cx: &mut ReadCx<'_>, input: Input, _source_id: String, ) -> Result<LocatedExpr>

Decode input into a LocatedExpr, attributing spans to source_id.

impl LocatedEncoder for BinaryCodec

fn encode_located( &self, cx: &mut WriteCx<'_>, expr: &LocatedExpr, ) -> Result<Output>

Encode a LocatedExpr, optionally using its origin for fidelity.

impl TreeDecoder for BinaryCodec

fn decode_tree( &self, cx: &mut ReadCx<'_>, input: Input, _source_id: String, ) -> Result<LocatedExprTree>

Decode input into a LocatedExprTree, attributing spans to source_id.

impl TreeEncoder for BinaryCodec

fn encode_tree( &self, cx: &mut WriteCx<'_>, expr: &LocatedExprTree, ) -> Result<Output>

Encode a LocatedExprTree, reproducing layout and trivia where present.
