Feature Tour

Runnable examples pull live source from sbe-feature-tour (compiled by docs_validation_test). Schematics that cannot run in the harness stay rust,ignore.

• Exact Sizing — compute_length_with_header before you encode
• Bulk Arrays — bulk_add(&[Entry]) for fixed-stride leaf groups
• Decoder Lanes — random access, staged into_*, ordered callbacks, .memoized()
• What Generated Code Looks Like — stages, metadata, reserved names
• Trust Boundaries — try_* → Result; wrap panics if short; decode is hybrid
• Domain Objects (DTOs) — owned snapshots (never on the hot path)
• Multi-Template Dispatch — AnyMessage routes by template ID
