Rejection of loose or contradictory graph-construction controls.

Variants

DegreeOrder

The target degree was zero or exceeded the hard persisted cap.

Fields

r_target: u8

Normal pruned degree.

r_max: u8

Hard persisted cap.

AlphaOrder

Alpha values were non-finite, below one, or decreased on refinement.

Fields

alpha_build: f32

First-pass alpha.

alpha_refine: f32

Second-pass alpha.

ConstructionWidth

The construction beam was zero or narrower than the target degree.

Fields

l_build: u16

Construction beam width.

r_target: u8

Normal pruned degree.

CheckpointBatchRows

A checkpoint batch must contain at least one row.

Trait Implementations

impl Clone for GraphParamsError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for GraphParamsError

impl Debug for GraphParamsError

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

Formats the value using the given formatter.

impl Display for GraphParamsError

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

impl Error for GraphParamsError

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.

impl PartialEq for GraphParamsError

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

Equality operator ==.

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

Inequality operator !=.
