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

[−]

pub enum ExistenceRequirement {
    KeepAlive,
    AllowDeath,
}

[−]

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

Variants

KeepAlive

[−]

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.

AllowDeath

[−]

Operation may result in account going out of existence.
