# First-release API and SemVer audit

Generated by `metacrate-ci-matrix api-baseline-write`; do not edit by hand.

The compatibility source is pinned at [`2aa70bb68513b39795da5d13c88f31b86e85a3ba`](https://github.com/cinderblocks/libremetaverse/tree/2aa70bb68513b39795da5d13c88f31b86e85a3ba). The baseline version is `0.0.1`.

## Coverage and quality decisions

- Mapped/exported public types: **3066 / 3066**; unexplained mappings: **0**.
- Mapped/exported public members: **30789 / 30789**; duplicate destinations: **0**.
- Rust naming and ownership: mapped function/constant names follow Rust conventions and every member uses a reviewed ownership term.
- External signature types: **142**; referenced support traits: **2**; accidental dependency types exposed by mapped signatures or public Rust declarations: **0**.
- Intentional delegate APM replacements: **80**; each uses a native callback and is compiled by the downstream fixture.
- Descriptively named overloads: **7151**; names remain fixed by the mapping ledger.
- Native `async fn` mappings: **334**; boxed object-safe trait futures with explicit `Send`: **26**.
- Callback signatures requiring `Send + Sync`: **137**; reviewed dyn-compatible thread-safe boundary traits: **6** (`IGridClient`, `IBakingTextureProvider`, `ICurrentOutfitPolicy`, `IRlvActionCallbacks`, `IRlvQueryCallbacks`, and `IVoiceLogger`).
- C# enum mappings: **243** (46 unknown-bit-retaining flag types); stable public error enums marked `non_exhaustive`: **7**.

The exact mapping, exported-marker, feature, and normalized Rust declaration hashes are stored in [`SEMVER-BASELINE.json`](SEMVER-BASELINE.json). A change must be reviewed and classified before the baseline is re-recorded.

## Intentional Rust migration recipes

- C# `PascalCase` methods/properties become Rust `snake_case`; overloads use the ledger's stable descriptive suffix, never argument-count dispatch.
- C# reference ownership becomes owned values, shared or mutable borrows, `Arc`-backed managers, and explicit optional values as recorded per member.
- `Task<T>` becomes `async fn -> Result<T, Error>`; object-safe async traits return `Pin<Box<dyn Future<Output = Result<...>> + Send + '_>>`.
- .NET events become `subscribe_*` calls returning an owned `Subscription`; callbacks are `Send + Sync` and dispatch outside internal locks.
- `IDisposable` becomes explicit idempotent shutdown plus `Drop`; cancellation remains a typed `Error::Cancelled`.
- Closed C# enums retain fixed discriminants and are SemVer-breaking to extend; flags retain unknown bits, while public Rust error enums are `non_exhaustive`.
- Pure-Rust image backends are enabled by default (`rust-j2k`, `rust-skia`); native alternatives remain feature-gated (`jpeg2000`, `skia`, `vorbis`, `real-audio`), and empty-default sets remain part of the baseline.
- Capability HTTP injection uses project-owned `HttpMessageHandler`, `CapsHttpLimits`, and `with_native_transport`; the internal `reqwest` client is not part of the public surface.
- External C# signature types map to core/std, adopted cross-platform crates, or project-owned boundary types; no third-party crate path leaks through mapped signatures or public Rust declarations.

## Compile consumers

- `tests/api-compile` compiles every mapped type/member from a standalone downstream workspace.
- `tests/semver-port` is a runnable representative port covering lifecycle, value types, structured data, imaging, RLV, cancellation, dyn trait, and `Send`/`Sync` contracts without network access.
