Expand description

Constants that change the behavior of the protocol.

The value of each constant here must be fixed for a given protocol version. To change the value of a constant, advance the protocol version, and add support for it in get_for_version under the new version number. (below).

To add a new field to this struct, use the following procedure:

Advance the protocol version.
Add the field as a private Option<T> to the struct.
Initialize the field to None in prior protocol versions.
Initialize the field to Some(val) for your new protocol version.
Add a public getter that simply unwraps the field.
Two public getters of the form field(&self) -> field_type and field_as_option(&self) -> Option<field_type> will be automatically generated for you. Example for a field: new_constant: Option<u64>

     pub fn new_constant(&self) -> u64 {
        self.new_constant.expect(Self::CONSTANT_ERR_MSG)
    }
     pub fn new_constant_as_option(&self) -> Option<u64> {
        self.new_constant.expect(Self::CONSTANT_ERR_MSG)
    }

With pub fn new_constant(&self) -> u64, if the constant is accessed in a protocol version in which it is not defined, the validator will crash. (Crashing is necessary because this type of error would almost always result in forking if not prevented here). If you don’t want the validator to crash, you can use the pub fn new_constant_as_option(&self) -> Option<u64> getter, which will return None if the field is not defined at that version.

If you want a customized getter, you can add a method in the impl.
