Struct ValueFormatter 

pub struct ValueFormatter<'a> { /* private fields */ }

Formatter for runtime values represented as KindedSlot.

Uses TypeSchemaRegistry to format TypedObject payloads with their schema-declared field names. Optionally accepts a reference resolver (Phase-2c) that dereferences ref-kind slots to their target values; absent the resolver, refs print as <ref>.

ADR-005 §1 single-discriminator preserved: heap arms are read via the slot’s typed pointer + HeapValue match (Q8 ruling). No per-heap-variant accessors on KindedSlot; no parallel sum types.

Implementations

impl<'a> ValueFormatter<'a>

pub fn new(schema_registry: &'a TypeSchemaRegistry) -> Self

Create a formatter without a reference resolver — Ref-kind slots will print as <ref>.

pub fn with_deref( schema_registry: &'a TypeSchemaRegistry, deref_fn: &'a dyn Fn(&KindedSlot) -> Option<KindedSlot>, ) -> Self

Create a formatter with a reference resolver. The resolver is invoked when a ref-kind slot is encountered; if it returns Some(target) the target is formatted in place, otherwise the ref prints as <ref>.

pub fn format_kinded(&self, slot: &KindedSlot) -> String

Primary entry point: format a runtime value to a string.

At the top level, raw strings render unquoted (so print("hi") prints hi, not "hi"). Inside containers (TypedObject fields, HashMap values, heap-array elements) strings are quoted via Self::format_kinded_nested.

pub fn format_kinded_nested(&self, slot: &KindedSlot) -> String

Format a runtime value as it appears nested inside another container — quotes string values to disambiguate {name: "alice"} vs {name: alice}.
