[Unreleased]

Added

• A declared minimum supported Rust version of 1.88, verified by running the test suite against it. The floor comes from the dependency graph (reqwest → url → idna → icu_*), not from this crate's own code. CI builds on both the MSRV and the pinned dev toolchain, plus an advisory job on latest stable that reports breakage from a new Rust release without gating pull requests.
• Wrappers for every one of the API's 34 Route::resource groups, plus users — 265 methods. See COVERAGE.md for the per-endpoint inventory.
• COVERAGE.md, a detailed record of what is wrapped, what is not, and why, checked against routes/api.php on the v5-stable branch.
• Retry with full-jitter exponential backoff, configurable through RetryPolicy and InvoiceNinjaClient::with_retry_policy. Defaults to 3 retries. Retry-After is honoured when the server sends it.
• InvoiceNinjaClient::with_timeout and a DEFAULT_TIMEOUT of 60 seconds applied to every request.
• Typed responses for previously untyped endpoints: Statics, StaticItem, Currency, DateFormat, SearchResults, SearchHit, HealthCheck, and PhpVersion.
• statics_as, search_as, and health_check_as as generic escape hatches for callers who need to pin a shape the typed models leave in extra.
• tests/client_requests.rs: 50 tests covering the request plumbing against a loopback wiremock server. No network or credentials required.
• RetryPolicy::max_elapsed, a ceiling on the time one call may spend across all attempts, defaulting to 120 seconds. The request timeout is per attempt, so without this the default policy could spend four minutes on a call that times out repeatedly.

Changed

• statics, search, and health_check return concrete types instead of being generic over T: DeserializeOwned.
• send_email now unwraps the data envelope, so T is the entity (Invoice, Quote, …) rather than a wrapper the caller had to model. It stays generic because the endpoint serves all four entity types.
• chart remains generic, deliberately: the eleven chart endpoints share no common response shape, so there is nothing to narrow to.
• The base URL is parsed and validated when the client is constructed. A missing scheme used to produce a 404 on every call instead of one error.
• list_all_* terminates on meta.pagination.total_pages when the server sends it, falling back to the short-page heuristic only when it does not.
• Error is now #[non_exhaustive], so later variants are not a breaking change. Matches on it need a catch-all arm.
• Error::Json is now a struct variant carrying an excerpt of the body that failed to decode. The serde message alone ("expected value at line 1 column 1") does not reveal that the response was, say, an HTML error page from a proxy or a login redirect from a wrong base URL.
• API errors with an empty or message-less body now report the status reason ("Not Found") instead of rendering blank.

Fixed

• list_all_* silently truncated results. The server caps page size at min(abs(per_page), 5000), so a page shorter than requested did not mean the last page — the walk stopped early and returned a partial list as though it were complete. per_page is now clamped to the server maximum so the fallback heuristic holds.
• list_all_* with per_page(0) never terminated: the check got < 0 has no solution. It now falls back to the default page size, and a MAX_PAGES backstop raises Error::PaginationLimit rather than quietly truncating.
• Requests could hang indefinitely. reqwest applies no timeout of its own and none was configured.
• Ids were interpolated into request paths unescaped, so a /, ?, or # in an id changed which endpoint was addressed.

Security

• Ids used as URL path segments are escaped, and ids that are empty or consist only of dots are rejected. Escaping alone is insufficient: the WHATWG rules the url crate implements decode %2E back to . before resolving dot segments, so an escaped .. still collapsed the path. An empty id would have addressed the collection route, making delete_client("") mean DELETE /clients.
• POST is never replayed on a 5xx or timeout, since the server may have applied it before the response was lost and a replay would duplicate an invoice, payment, or email. A 429 is the exception — the server states it refused the request, so no work was done.
• The API token and password are held as headers marked sensitive, so neither appears in Debug output. reqwest's own Client debug prints its default headers, so this is the only thing keeping the token out of logs; there is now a regression test pinning it.

[0.1.0] - 2026-10-23

Added

• Initial release: async client for the Invoice Ninja v5 API covering clients, invoices, quotes, credits, payments, products, expenses, projects, tasks, and vendors.
