Crate eure_schema 

Eure Schema types and structures

This library provides schema type definitions for Eure documents, following the specification in assets/eure-schema.schema.eure.

Type Variants

All types are variants of SchemaNodeContent:

Primitives:

• Text - Text type with optional language and length/pattern constraints
• Integer - Integer type with optional range and multiple-of constraints
• Float - Float type with optional range and multiple-of constraints
• Boolean - Boolean type (no constraints)
• Null - Null type
• Any - Any type (accepts any value)

Literal:

• Literal - Exact value match (e.g., status = "active")

Compounds:

• Record - Fixed named fields
• Array - Ordered list with item type
• Map - Dynamic key-value pairs
• Tuple - Fixed-length ordered elements
• Union - Tagged union with named variants

Reference:

• Reference - Type reference (local or cross-schema)
