Struct PythonCodec 

pub struct PythonCodec;

Runtime codec object for codec/python.

Trait Implementations

impl Decoder for PythonCodec

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

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

impl Default for PythonCodec

fn default() -> PythonCodec

Returns the “default value” for a type.

impl Encoder for PythonCodec

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

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

impl LocatedDecoder for PythonCodec

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 TreeDecoder for PythonCodec

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 PythonCodec

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

Encode a LocatedExprTree, reproducing layout and trivia where present.
