Typed rejection while resolving an adaptive or explicit ef.

Variants

ZeroK

Top-k must request at least one result.

KExceedsRows

Top-k exceeded the graph’s row count.

Fields

k: usize

Requested result count.

rows: usize

Available graph rows.

ExplicitBelowK

An explicit override was narrower than top-k.

Fields

k: usize

Requested result count.

ef: usize

Supplied traversal width.

ExplicitExceedsRows

An explicit override exceeded the graph’s row count.

Fields

ef: usize

Supplied traversal width.

rows: usize

Available graph rows.

ArithmeticOverflow

Adaptive multiplier arithmetic overflowed usize.

impl Eq for AdaptiveEfError

impl Error for AdaptiveEfError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
