Feature Tour

Runnable examples on these pages pull live source from the sbe-feature-tour sample crate (or a book/examples/ fragment compiled against the same codec). Those includes are compiled by docs_validation_test. Schematics that cannot run in the harness stay rust,ignore — see What Generated Code Looks Like.

• Exact Sizing — compute_length_with_header gives the byte count before you encode
• Bulk Arrays — bulk_add(&[Entry]) for fixed-stride leaf groups
• Consuming Decode Stages — walk groups and var-data in wire order
• What Generated Code Looks Like — stages, metadata, placement
• Trust Boundaries — try_from validates; wrap trusts — explicit in the types
• Domain Objects (DTOs) — owned, serialisable snapshots (never on the hot path)
• Multi-Template Dispatch — AnyMessage routes by template ID at decode time
