Expand description

This trait is intended to be implemented by types which embody the content of a key for a particular index collection.


  • Multiple types might be mappable into the key payload, and so implement this trait
  • This trait is only one way - from value into content
  • This trait uses a generic, because the same type might be usable as a key for multiple substates

Required Methods§


fn into_content(self) -> Payload::Content

Provided Methods§


fn into_key(self) -> Payload

Object Safety§

This trait is not object safe.
