Struct AdapterMeta 

pub struct AdapterMeta {

    pub tool_name: &'static str,
    pub display_name: &'static str,
    pub tool_version: &'static str,
    pub long_version: &'static str,
    pub about: &'static str,
    pub long_about: &'static str,
    pub after_help: &'static str,

}

Adapter-supplied runtime metadata that crap-core threads through parse_args, run, and the reporter call sites.

All fields are &'static because every production caller supplies env!(...) / build.rs-stamped literals or const &[&str] slices. Tests construct from &'static str literals too. The lifetime parameter was dropped in #161 — no caller ever needed non-static metadata, and the <'a> ripple polluted 15 function signatures for no payoff. The struct stays Copy so threading is trivial.

Reporters keep a flat (tool_name, tool_version) call boundary — the struct only travels through orchestration code.

Fields

tool_name: &'static str

Adapter binary name (e.g., "crap4rs", "crap4ts"). Drives clap’s --version output, the name field in SARIF, and the header line in table/markdown/html reporters.

display_name: &'static str

Human-readable adapter label (e.g., "Rust", "TypeScript"). Surfaced in the HTML reporter’s per-adapter footer row so end users read “Rust · cognitive complexity” instead of the binary name. Production binaries supply the language name; tests use a synthetic label. Distinct from tool_name because the binary’s package name is the wrong granularity for the adapter-provenance footer.

tool_version: &'static str

Short version string (e.g., "0.5.0"). Threaded to every reporter alongside tool_name.

long_version: &'static str

Long version string for --version --long (e.g., "0.5.0 (abc1234 2026-05-09)").

about: &'static str

Short adapter-flavored help text (one-line, shown by --help).

long_about: &'static str

Long adapter-flavored help text (multi-paragraph, shown by --help in full mode).

after_help: &'static str

after_help block with adapter-specific examples (crap4rs --coverage lcov.info ... etc.). May be empty.

coverage_hint: &'static str

Coverage-tool hint shown when --coverage points at a file with no SF: / DA: records. Adapter-specific because the remediation depends on the coverage toolchain (Rust: cargo llvm-cov --lcov; TS: c8 --reporter=lcov).

extensions: &'static [&'static str]

File extensions the walker should pick up (e.g., &["rs"] for crap4rs; &["ts","tsx","js","jsx","mjs","cjs"] for crap4ts). Adapter binaries supply a const &[&str]; copied into AnalyzeOptions.extensions at the orchestration boundary.

tool_info_uri: &'static str

Adapter repo URL spliced into SARIF’s runs[0].tool.driver.informationUri. Adapter-specific so crap4ts SARIF output links to crap4ts’s repo, not crap4rs’s.

rule_help_uri: &'static str

Adapter rule-help URL spliced into SARIF’s runs[0].tool.driver.rules[0].helpUri. Adapter-specific for the same reason as tool_info_uri.

config_file_name: &'static str

Conventional config file name the adapter binary auto-discovers in the working directory (e.g., "crap4rs.toml" for the Rust adapter; "crap4ts.toml" for the TS adapter). Threaded through to discover_config and surfaced in --view <preset> error hints so users see the right file name to create.

default_excludes: &'static [&'static str]

Commented-out exclude patterns emitted by init into the generated config (e.g., &["tests/**", "benches/**", "examples/**"] for Rust; &["node_modules/**", "dist/**", "coverage/**"] for TS). Adapter-specific because the convention for “where tests and ignorable artifacts live” differs per ecosystem. May be empty — init then emits the # exclude = [ … ] block without per-language entries.

This field is init-template only — it does NOT affect the analyzer’s effective exclude list at runtime. The runtime exclude list is built from cli.filter.exclude plus the user’s crap4ts.toml/crap4rs.toml exclude entries, with adapter- mandated patterns prepended via forced_excludes (below).

forced_excludes: &'static [&'static str]

Adapter-mandated exclude patterns prepended to every analysis run, regardless of CLI flags or user config. Use for files that are structurally never source for the adapter’s language — e.g. crap4ts sets &["**/*.d.ts"] because TypeScript declaration files contain only ambient types, never executable code. crap4rs has no such suffix today and sets &[].

Distinct from default_excludes (above): forced excludes are load-bearing at analysis time and cannot be turned off by the operator, whereas default_excludes is init-template scaffolding. If an operator genuinely needs .d.ts files in their report, the path is forking the adapter or filing a follow-up to add an opt-out — not a config knob (crap-rs#253).

default_metric: ComplexityMetric

The default complexity metric the adapter binary uses when neither CLI nor config file specifies one. crap4rs sets Cognitive; crap4ts sets Cyclomatic (the only metric crap4ts currently supports per CrapError::MetricNotSupported). Threaded through merge_effective_inputs so the binary’s default flips per adapter without re-litigating the shared CLI fallthrough. See ADR (d) adr-adapter-meta-default-metric.md for the design rationale (per-adapter defaults surface through AdapterMeta, not crap-core configuration).

Implementations

impl AdapterMeta

pub fn extensions_owned(&self) -> Vec<String>

Allocate an owned Vec<String> from extensions for inclusion in AnalyzeOptions (which owns its config rather than borrowing from the meta, decoupling analysis lifetime from CLI lifetime).

Trait Implementations

impl Clone for AdapterMeta

fn clone(&self) -> AdapterMeta

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AdapterMeta

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Copy for AdapterMeta
