[][src]Enum frame_support::traits::ExistenceRequirement

pub enum ExistenceRequirement {

Simple boolean for whether an account needs to be kept in existence.



Operation must not result in the account going out of existence.

Note this implies that if the account never existed in the first place, then the operation may legitimately leave the account unchanged and still non-existent.


Operation may result in account going out of existence.
