    fn generate_with_entropy(

        entropy: Self::Entropy

Expand description

Trait for keys that can be generated

The same rules about ScriptContext and ValidNetworks from IntoDescriptorKey apply.

This trait is particularly useful when combined with DerivableKey: if Self implements it, the returned GeneratedKey will also implement it. The same is true for IntoDescriptorKey: the generated keys can be directly used in descriptors if Self is also IntoDescriptorKey.

Associated Types

Type specifying the amount of entropy required e.g. [u8;32]

Extra options required by the generate_with_entropy

Returned error in case of failure

Required methods

Generate a key given the extra options and the entropy

Provided methods

Generate a key given the options with a random entropy
