Struct AlgolShapeParser 

pub struct AlgolShapeParser { /* private fields */ }

ShapeExprParser adapter that parses string input with an Algol PrattTable.

This lets callers build a PrattShape over the real Algol parser instead of carrying a local test-only adapter. The parser returns the raw Pratt expression tree; number-domain lowering belongs to codec decode paths that have a runtime context.

Implementations

impl AlgolShapeParser

pub fn new(table: PrattTable) -> Self

Build an adapter backed by table.

pub fn table(&self) -> &PrattTable

Return the Pratt table used by this adapter.

Trait Implementations

impl ShapeExprParser for AlgolShapeParser

fn label(&self) -> &str

A short human-readable name for this parser, shown in shape descriptions.

fn parse_expr(&self, source: &str) -> Result<Expr>

Parse source text into an expression to match against the inner shape.

fn is_effectful(&self) -> bool

Whether parsing may run effects; false by default.
