Module value 

Core value types for Shape

This module defines supporting types used throughout the Shape runtime and VM. The canonical runtime value representation is ValueWord (8-byte NaN-boxed).

Structs

HostCallable

A callable closure backed by native Rust code with captured state. Used by extension modules to return objects with callable methods (e.g., DbTable.filter).

PrintResult

Print result with structured spans for reformattable output

VTable

Virtual method table for trait objects.

Enums

FilterLiteral

A literal value in a filter expression (for SQL generation)

FilterNode

Filter expression tree for SQL pushdown. Built from ExprProxy comparisons and logical operations.

FilterOp

Comparison operator for filter expressions

PrintSpan

A span in print output (literal text or formatted value)

Upvalue

Upvalue - a captured variable that can be shared between closures and their enclosing scope.

VTableEntry

An entry in a vtable — how to dispatch a method call

Functions

vmarray_from_nanboxed

Backward-compatibility alias.

vmarray_from_value_words

Create a VMArray from an iterator of ValueWord values.

Type Aliases

VMArray

Type alias for array storage — ValueWord elements for 9x memory reduction.
