AlgolCodec

Struct AlgolCodec 

Source
pub struct AlgolCodec { /* private fields */ }
Expand description

Runtime decoder and encoder for the Algol surface, wrapping a PrattParser over crate::default_pratt_table.

Implements the Decoder, LocatedDecoder, TreeDecoder, Encoder, and TreeEncoder traits so the codec participates in every decode/encode lane: it parses infix text into checked Expr forms and renders any Expr back to infix text.

Trait Implementations§

Source§

impl Decoder for AlgolCodec

Source§

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

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

impl Default for AlgolCodec

Source§

fn default() -> Self

Returns the “default value” for a type. Read more
Source§

impl Encoder for AlgolCodec

Source§

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

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

impl LocatedDecoder for AlgolCodec

Source§

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

Decode input into a LocatedExpr, attributing spans to source_id.
Source§

impl TreeDecoder for AlgolCodec

Source§

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

Decode input into a LocatedExprTree, attributing spans to source_id.
Source§

impl TreeEncoder for AlgolCodec

Source§

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

Encode a LocatedExprTree, reproducing layout and trivia where present.
