Enum frame_support::traits::tokens::Preservation
source · pub enum Preservation {
Expendable,
Protect,
Preserve,
}
Expand description
The mode by which we describe whether an operation should keep an account alive.
Variants§
Expendable
We don’t care if the account gets killed by this operation.
Protect
The account may not be killed, but we don’t care if the balance gets dusted.
Preserve
The account may not be killed and our provider reference must remain (in the context of tokens, this means that the account may not be dusted).
