Crate skipper_core 

Core of Skipper: test-gating via Google Spreadsheet.

Most users want the get-skipper crate (the #[skipper] attribute) or skipper-cucumber. This crate holds the shared pieces: the resolver, the Google Sheets client, the sync writer, caches and the quarantine report.

Structs

CacheManager

Temp directory shared between the orchestrating process (cargo skipper) and the test binaries: it holds the resolver handoff (cache.json) and one JSON array of discovered test IDs per writer.

Error

Error type for every fallible Skipper operation.

FetchAllResult

The primary sheet plus all entries merged with the reference sheets.

HttpSheetsApi

Sheets API over HTTPS, authenticated with a service-account JWT (OAuth 2.0 jwt-bearer grant). The access token is cached until shortly before it expires.

Report

Quarantine-debt summary emitted at the end of a run.

ServiceAccountCredentials

The fields of a Google service-account JSON key.

SheetFetchResult

A single fetched sheet.

SheetsWriter

Reconciles the primary sheet with the test IDs discovered in a run: new IDs are appended (empty disabledUntil); stale rows of the same files are deleted only with SKIPPER_SYNC_ALLOW_DELETE=true. Existing rows are never modified.

SkipperConfig

Configuration shared by the resolver and the writer.

SkipperResolver

Decides whether a test runs. Tests not in the spreadsheet always run (opt-out model); a test with a future disabledUntil is skipped.

TestEntry

One spreadsheet row.

Enums

Credentials

Google service-account credentials, in one of three formats.

SkipperMode

Operating mode, read from SKIPPER_MODE.

Traits

SheetsApi

The four Google Sheets v4 calls Skipper needs. Implemented over HTTP by HttpSheetsApi; tests can provide an in-memory fake.

Functions

build_markdown_summary

build_report

entries: resolver state; suppressed: IDs skipped in this run; re_enabled: IDs that ran although listed with an already expired date.

build_test_id

relative/path.rs > part1 > part2. The path is made relative to the project root (see find_project_root) and always uses /.

debug_enabled

True when SKIPPER_DEBUG is set to a non-empty value.

emit_summary

Append the markdown to $GITHUB_STEP_SUMMARY (else print it to stdout) and write skipper-report.json in the current directory.

fetch_all

Fetch the primary sheet and merge every reference sheet into it. A failing reference sheet is skipped with a warning; a failing primary is an error.

find_project_root

Outermost ancestor whose Cargo.toml declares [workspace], else the nearest directory with a Cargo.toml, else start itself.

log

Debug log to stderr, only when SKIPPER_DEBUG is set.

normalize_test_id

Canonical form used for every lookup: trim, lowercase, collapse whitespace.

parse_disabled_until

Parse a disabledUntil cell. Only strict YYYY-MM-DD is accepted; the result is midnight UTC of the following day, so the test stays disabled for the whole calendar day. Empty means no date. row (1-based sheet row, 0 = unknown) only appears in the error message.

relative_to_root

Make file relative to the project root. Relative paths (what file!() yields for workspace members) are kept as they are.

warn

Warning to stderr, only when SKIPPER_DEBUG is set.
