skif-core 0.1.1

//! Core diagnostic, fix and report types for skif.
//!
//! This crate is an implementation detail of `skif`: it carries no stability promise of its own. Depend on the
//! `skif` facade, which re-exports what is meant to be used.
//!
//! The crate is library-first and deliberately free of side effects:
//!
//! - **No IO outside [`fs`].** Nothing else here reads or writes files. Paths are workspace-relative [`std::path::PathBuf`]s that the
//!   caller resolves; fixes are described as data ([`FixOp`]) and only [`apply_text_edits`] touches text, in memory.
//! - **Plain serde data.** Every type is `Serialize`/`Deserialize` with kebab-case names, so reports can be emitted
//!   as JSON and fixes can cross process boundaries unchanged. The `schema` feature adds `schemars` derives.
//! - **Poly-compatible spans.** A [`Span`] is a half-open UTF-8 byte range plus 1-based line and column numbers
//!   (columns count Unicode scalar values). [`LineIndex`] converts offsets, including UTF-16 columns for SARIF.
//!
//! The [`fs`] module holds the read-only [`FileSystem`] abstraction with its disk ([`OsFs`]) and in-memory
//! ([`MemoryFs`]) implementations; it is the only code that touches the disk.
//!
//! A rule produces [`Diagnostic`]s; each may carry alternative [`Fix`]es (the first is preferred) made of
//! structured [`FixOp`]s. [`Report::new`] sorts diagnostics deterministically and computes a [`Summary`].
//!
//! ```
//! use skif_core::{Diagnostic, Location, Report, RuleId, Severity};
//!
//! let diagnostic = Diagnostic::new(
//!     RuleId::new("unused-dependency").unwrap_or_else(|_| RuleId::from_static("fallback")),
//!     Severity::Warning,
//!     "dependency is never imported",
//!     Location::file("package.json"),
//! );
//! let report = Report::new(vec![diagnostic], 1);
//! assert_eq!(report.summary.warnings, 1);
//! ```
