Struct ErrorPropGenerator

pkg/codegen/error_prop.go:52–58

ErrorPropGenerator generates Go code for error propagation expressions (expr?). Basic Transforms: let data = readFile(path)? Into: tmp, err := readFile(path) if err != nil { return zeroVal1, zeroVal2, ..., err } data := tmp Context Transform (? "message"): let order = fetchOrder(id)

//   - Second: tmp1, err1
//   - Third: tmp2, err2
type ErrorPropGenerator struct {
	*BaseGenerator
	Expr        *ast.ErrorPropExpr
	ReturnTypes []string // Zero values for non-error return types
	Counter     int      // For generating unique variable names
	NeedsFmt    bool     // Set to true if fmt.Errorf is generated (caller should add import)
}

// NewErrorPropGenerator creates a new error propagation code generator.
