Enum FetchFailure 

pub enum FetchFailure {
    Actionable(String),
    Transient,
    NotAttempted,
}

Outcome of a registry fetch attempt for one dependency, as recorded in DocumentState::outcomes (deps-lsp) and rendered by crate::lsp_helpers::generate_diagnostics_from_cache (#478).

Replaces a bare HashSet<PackageName> membership check so the per-dependency diagnostic can distinguish a failure with a safe, user-actionable hint from an opaque one, without ever threading raw, potentially IP-bearing error text into the diagnostic (see DepsError::fetch_failure).

Variants

Actionable(String)

The fetch failed with a pre-vetted, safe-to-display hint (currently only produced from DepsError::RateLimited).

Transient

The fetch failed for a reason with no safe user-facing detail to show — the diagnostic falls back to a generic “lookup failed” message.

NotAttempted

The dependency was never actually queried (e.g. a name/source collision detected before the fetch, see deps-lsp’s dedup_dependencies_by_source) — renders the same generic “lookup failed” message as Self::Transient, since the absence of an attempt is not evidence the package doesn’t exist.

Trait Implementations

impl Clone for FetchFailure

fn clone(&self) -> FetchFailure

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FetchFailure

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

Formats the value using the given formatter.

impl Eq for FetchFailure

impl PartialEq for FetchFailure

fn eq(&self, other: &FetchFailure) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
