A collection of errors that Perestroika can generate.

Variants

ConnectionAlreadyExists

Raised when trying to create a Connection which already exists in a Genome.

Fields

source: usize

The source Node.

target: usize

The target Node.

ConnectionMissingSource

Raised when a Connection is missing a source Node.

ConnectionMissingTarget

Raised when a Connection is missing a target Node.

ConnectionSourceAndTargetSameDepth

Raised when a Connection has the soure and target Nodes are on the same depth.

Fields

depth: DepthType

The depth of the Layer.

ConnectionSourceAndTargetAreSame

A more specific version of ConnectionSourceAndTargetSameDepth.

ConnectionSourceDeeperThanTarget

Raised when a Connection has a source Node deeper than the target Node.

Fields

source: DepthType

The depth of the source Node.

target: DepthType

The depth of the target Node.

GenomeMissingNodes

Raised when a Genome is created without Nodes.

A Genome must have at least two Layers, an Input and Output, on each at least a single Node.

GenomeWithoutInputNodes

Raised when a Genome is created without Input Nodes.

GenomeWithoutOutputNodes

Raised when a Genome is created without Output Nodes.

GenomeMissingConnections

Raised if an operation on a Genome requires Connections, but the Genome has none.

GenomeMaxNodesReached

Raised when an operation on a Genome tries to create a new Node, but the Genome has the maximum amount of Nodes.

GenomeMaxConnectionsReached

Raised when an operation on a Genome tries to create a new Connection, but the Genome has the maximum amount of Connections.

GenomeIsTooShallow

Raised when an operation on the Genome tries to access a hidden layer, but there are none.

LayerMustHaveMoreThanOneNode

Raised when an operation on a Genome requires a removal of a Node from a Layer, but the Layer has a single Node.

LayerInputLengthMismatch

Raised when a Genome tries to propagate the inputs but the input’s length differs from the input Layer’s length.

Fields

expected: usize

The expected length of the InputLayer.

got: usize

The actual received length of the InputLayer.

LayerDoesNotExist

Raised when a Layer that does not exist is being used or called.

UnhandledError

An error that currently does not have a dedicated name.

Fields

text: String

Text of the undocumented error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
