Struct ValueFormatter 

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

Formatter for ValueWord values

Uses TypeSchemaRegistry to format TypedObjects with their field names. Optionally accepts a reference resolver to dereference &ref values (requires VM stack access, so only available during execution).

Implementations

impl<'a> ValueFormatter<'a>

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

Create a new formatter

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

Create a formatter with a reference resolver.

The resolver is called when a NanTag::Ref or HeapValue::ProjectedRef is encountered, allowing the formatter to print the underlying value instead of <ref>.

pub fn format_nb(&self, value: &ValueWord) -> String

Format a ValueWord value to string — primary entry point.

Uses NanTag/HeapValue dispatch for inline types (f64, i48, bool, None, Unit) and heap types (String, Array, TypedObject, Decimal, etc.).
