v0.4.0+api-spec-0.3.0-2026-05-04

cloud-hypervisor-client

Added

• Two new generated API operations on DefaultApi, regenerated from a newer revision of the upstream cloud-hypervisor
  OpenAPI spec (still self-labelled 0.3.0):
  • vm_add_generic_vhost_user_put (PUT /vm.add-generic-vhost-user)
  • vm_resize_disk_put (PUT /vm.resize-disk)
• New generated models: ConsoleMode, CoreSchedulingMode, GenericVhostUserConfig, ImageType, LockGranularity,
  MemoryRestoreMode, TimeoutStrategy, UserDeviceConfig, VmResizeDisk, VmState.
• Various new optional fields on existing *Config models from the same regeneration pass; see commit b1c3cb0 for
  the full set.

Changed

• Breaking. Bumped MSRV from 1.81.0 to 1.86.0 and migrated the library crate to Rust edition 2024.
• Breaking. Dropped HTTP authentication from the public surface. apis::configuration::Configuration no
  longer exposes basic_auth, oauth_access_token, or api_key, and the BasicAuth alias and ApiKey struct
  are gone. The cloud-hypervisor REST API speaks over a Unix domain socket and defines no securitySchemes, so
  these fields had no effect against cloud-hypervisor itself. Callers that constructed Configuration as a struct
  literal must drop the auth initializers. Anyone tunneling through an authenticating proxy can attach headers on
  the hyper::Client passed to Configuration::with_client.
• Bumped the http dependency from ~0.2 to 1. The library only references http::header::InvalidHeaderValue,
  http::Error, and http::uri::InvalidUri (in apis::Error variants), all of which exist with identical shape
  in http 1.x. Aligns the dep tree with the http 1.x already pulled in transitively by hyper 1.x.
• ConsoleConfig::mode and DebugConsoleConfig::mode now use the shared models::ConsoleMode enum instead of
  per-struct inline Mode enums. Callers constructing these configs need to switch to models::ConsoleMode::*.
• VmInfo::state now uses models::VmState instead of an inline per-struct State enum.

Removed

• models::SgxEpcConfig (dropped from the upstream spec).
• base64 runtime dependency. Its only call site was base64::encode in the Auth::Basic arm of request.rs,
  which the auth removal above eliminates.

generator

Added

• Generator config maps unsigned integer schema types (uint8 / uint16 / uint32 / uint64) to their Rust
  counterparts (u8 / u16 / u32 / u64) instead of the signed types OpenAPI Generator otherwise picks (#3).
• Generator performs a pre-flight check against Maven Central and emits a tracing::warn! when a newer
  openapi-generator-cli release is available than the pinned one.
• Top-level Justfile with a just gen recipe that drives the code generator from the repo root.
• templates/hyper/configuration.mustache override, driving the auth removal from generated code.

Changed

• Generator binary (generator/src/main.rs) anchors its workdir to CARGO_MANIFEST_DIR rather than the current
  working directory, so it can be invoked from anywhere (e.g. cargo run --manifest-path generator/Cargo.toml from the
  repo root).
• The generator source is now spread across multiple modules with main.rs only acting as a thin orchestrator.
• Constants for the generator/spec versions and URLs are now lifted to the top of module file.
• Bumped the OpenAPI Generator CLI pinned by the generator from 7.12.0 to 7.22.0. Regenerated the
  templates_original/ baseline against 7.22.0; generated src/ is byte-identical for the current spec.
• Generator dependencies updated, including new entries for quick-xml, semver, and serde (used by the new
  release check).
• Switched the error-handling library from anyhow to rootcause (with the rootcause-backtrace and
  rootcause-tracing companions). main() now installs both hooks at startup so error reports automatically
  capture a backtrace and the active tracing spans, and tracing_init adds RootcauseLayer to the subscriber so
  span fields are recorded.

Removed

• Runtime check that required the git checkout to literally be named cloud-hypervisor-client.
• Local generator/workdir/templates/hyper/api.mustache and generator/workdir/templates/model.mustache. They had
  no intentional overrides and were stale 7.12.0-era copies; the generator now uses the embedded 7.22.0 versions via
  OpenAPI Generator's --template-dir fallback.
