Crate schema 

Replication schema and field codec definitions for the sdec codec.

This crate defines how game state is represented for replication:

• Schema model for entity types, components, and fields
• Field codecs (bool, integers, fixed-point, varints)
• Quantization and threshold configuration
• Deterministic schema hashing

Design Principles

• Runtime-first - v0 uses runtime schema building, derive macros come later.
• Explicit schemas - No reflection on arbitrary Rust types.
• Deterministic hashing - Schema hash is stable given the same definition.

Structs

FieldCodec

Codec configuration for a single field.

Enums

FieldKind

The kind of encoding for a field.

Functions

schema_hash

Computes a deterministic hash for schema validation.

Type Aliases

ComponentId

A component ID within a schema.

FieldId

A field ID within a component.
