Expand description

Error enum used for various recoverable errors

Variants

NoSuchNode(usize)

Emitted whenever a change involving a non-existent node has been requested.

BadWeight(f64)

Emitted when the link weight is not in (0, 1].

LinkToSelf(usize)

Emitted when an attempt is made to link a node to itself.

BadProbability(f64)

Emitted when constant probability is not in (0, 1].

NodeExists(usize)

Emitted when an attempt is made to attach a node which already exists.

NoTarget

Emitted when an attempt is made to run an algorithm requiring at least 1 target without targets.

NotWhole

Emitted when the network is required to be whole, but is not.
