Struct ExprRoundTripCase 

pub struct ExprRoundTripCase {
    pub symbol: Symbol,
    pub language: Symbol,
    pub source: String,
    pub expected_display: Option<String>,
    pub affects_badge: Option<Symbol>,
}

Codec-faithful source case that decodes to the shared Expr graph.

The case records source text plus the canonical display expected from the decoded expression. A missing expected display means successful decoding is enough; a language-specific decoder returns Ok(None) for an explicit gap.

Fields

symbol: Symbol

Stable symbol identifying this case.

language: Symbol

Language exercised by this case.

source: String

Source text.

expected_display: Option<String>

Expected canonical display of the decoded expression.

affects_badge: Option<Symbol>

Fidelity badge affected by this case, if any.

Implementations

impl ExprRoundTripCase

pub fn run_expr_round_trip( &self, cx: &mut Cx, decode_fn: impl Fn(&mut Cx, &str) -> Result<Option<Expr>>, ) -> ExprRoundTripObservation

Runs this case using decode_fn to decode source into an expression.

pub fn run( &self, cx: &mut Cx, decode_fn: impl Fn(&mut Cx, &str) -> Result<Option<Expr>>, ) -> ExprRoundTripObservation

Runs this case using decode_fn to decode source into an expression.

Trait Implementations

impl Clone for ExprRoundTripCase

fn clone(&self) -> ExprRoundTripCase

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ExprRoundTripCase

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for ExprRoundTripCase

impl PartialEq for ExprRoundTripCase

fn eq(&self, other: &ExprRoundTripCase) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
