pub trait Fork: Serialize + DeserializeOwned + Clone + Sized {

Expand description

A ChainSpec extension fork definition.

Basically should look the same as Group, but all parameters are optional. This allows changing only one parameter as part of the fork. The forks can be combined (summed up) to specify a complete set of parameters

Required Associated Types§

source

type Base: Group<Fork = Self>

A base Group type.

Required Methods§

source

fn combine_with(&mut self, other: Self)

Combine with another struct.

All parameters set in other should override the ones in the current struct.

source

fn to_base(self) -> Option<Self::Base>

Attempt to convert to the base type if all parameters are set.

Object Safety§

This trait is not object safe.
