Enum frame_support::traits::tokens::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.

Trait Implementations

impl Clone for ExistenceRequirement

fn clone(&self) -> ExistenceRequirement

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExistenceRequirement

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

Formats the value using the given formatter.

impl PartialEq<ExistenceRequirement> for ExistenceRequirement

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

This method tests for self and other values to be equal, and is used by ==.

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

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