Errors returned by the bin-packing solvers.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidInput(String)

The problem failed input validation (e.g. empty demand list, zero dimension, invalid cost).

Unsupported(String)

The requested solver configuration is not currently supported.

Infeasible1D

A 1D demand cannot fit any declared stock entry.

Fields

item: String

Name of the demand that could not be placed.

length: u32

Length of the demand that triggered the infeasibility.

Infeasible2D

A 2D demand cannot fit any declared sheet entry, even with rotation.

Fields

item: String

Name of the demand that could not be placed.

width: u32

Width of the demand that triggered the infeasibility.

height: u32

Height of the demand that triggered the infeasibility.

Infeasible3D

A 3D demand cannot fit any declared bin entry, even with rotation.

Fields

item: String

Name of the demand that could not be placed.

width: u32

Width of the demand that triggered the infeasibility.

height: u32

Height of the demand that triggered the infeasibility.

depth: u32

Depth of the demand that triggered the infeasibility.

Trait Implementations

impl Debug for BinPackingError

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

Formats the value using the given formatter.

impl Display for BinPackingError

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

Formats the value using the given formatter.

impl Error for BinPackingError

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.
