Struct SlowRoot 

pub struct SlowRoot { /* private fields */ }

The resolved directories, how they were learned, and what may be claimed about each.

Implementations

impl SlowRoot

pub fn resolve(data_root: &Path, config: Option<&LayoutConfig>) -> SlowRoot

Resolve every directory from the config, or fall back under the data root when there is none.

pub fn source(&self) -> Source

How gunnar learned where to write.

pub fn serialdat(&self) -> &str

serialdat.mountpoint, or empty when nothing said. Reported only.

pub fn class(&self) -> &str

serialdat.class — p3 / device / fallback — or empty when nothing said. A class that was not read is not reported as one.

pub fn device(&self) -> &str

serialdat.dev, or empty.

pub fn path_of(&self, name: &str) -> PathBuf

The path for one dir.<name>, exactly as configured. Never computed relative to anything else.

pub fn claim(&self) -> Claim

The one verdict, over the copies that need another failure domain.

The three of them are laid by one installer decision, so they agree by construction; if they ever did not, the honest summary is the WORST of them, never the best.

pub fn claim_of(&self, name: &str) -> Claim

The verdict for one directory.

pub fn dir(&self, name: &str) -> Result<PathBuf>

One of the directories, created on demand.

Creation is here and not at resolve time on purpose: a slow area that has gone read-only must fail the write that needed it, with the path in the message, rather than fail the boot of a server whose git objects are all still on a working disk.

pub fn meta_dir(&self) -> Result<PathBuf>

The metadata mirror: roster, principals, enrolled keys. Needs off-stripe.

pub fn crash_dir(&self) -> Result<PathBuf>

Crash records and diagnostics. Needs off-stripe.

pub fn log_dir(&self) -> Result<PathBuf>

The audit trail and the durable console log. Needs off-stripe.

pub fn gc_dir(&self) -> Result<PathBuf>

gc / repack scratch. Does not need off-stripe; nothing writes here yet.

pub fn quarantine_dir(&self) -> Result<PathBuf>

Push quarantine. Does not need off-stripe; nothing writes here yet.

pub fn health_line(&self, what: &str, dir: &str) -> String

The honest sentence about one off-stripe-requiring copy.

Never “OK” and never “missing” for a copy that is present on the same device: the whole failure this module exists to prevent is a health check that answers mirror OK for a mirror that dies with its original.

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

The three off-stripe-requiring copies, each said honestly.

pub fn row(&self) -> (String, bool)

The console row: the same shape crate::disktest uses, one line, and a warn flag so the dashboard colours it.

pub fn announce(&self, config_path: &str, authenticity: &str)

Say the row as the ONE tracing line the log tap turns into the layout row (dashboard::describe), exactly as disktest does.

authenticity is crate::layout_config::Authenticity::word — the SAME two words the installer’s own console prints, so an admin comparing the two screens is not left wondering whether they mean the same thing.
