impl GetEraValidatorsError
sourcepub fn is_era_validators_missing(&self) -> bool
pub fn is_era_validators_missing(&self) -> bool
Returns true
if the result represents missing era validators.
Trait Implementations§

impl DataSize for GetEraValidatorsError
source§const IS_DYNAMIC: bool = true
const IS_DYNAMIC: bool = true
If
true
, the type has a heap size that can vary at runtime, depending on the actual value.source§const STATIC_HEAP_SIZE: usize = 0usize
const STATIC_HEAP_SIZE: usize = 0usize
The amount of space a value of the type always occupies. If
IS_DYNAMIC
is false, this is
the total amount of heap memory occupied by the value. Otherwise this is a lower bound.source§fn estimate_heap_size(&self) -> usize
fn estimate_heap_size(&self) -> usize
Estimates the size of heap memory taken up by this value. Read more
