## Fory IDL Schema

Define cross-language data structures with Fory IDL and generate native code for multiple languages.

- [Fory IDL Overview](compiler/index.md) - Introduction and quick start
- [Fory Schema IDL](compiler/schema-idl.md) - Complete language syntax
- [Type System](compiler/schema-idl.md#type-system) - Primitive types, collections, and mappings
- [Compiler Guide](compiler/compiler-guide.md) - CLI usage and build integration
- [Generated Code](compiler/generated-code.md) - Output format for each language
- [Protocol Buffers vs Fory IDL](compiler/protobuf-idl.md) - Feature comparison and migration

## Serialization Format
