Enum Preservation

pub enum Preservation {
    Expendable,
    Protect,
    Preserve,
}

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).

Trait Implementations

impl Clone for Preservation

fn clone(&self) -> Preservation

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Preservation

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Preservation

fn eq(&self, other: &Preservation) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
