Struct frame_election_provider_support::bounds::DataProviderBounds

pub struct DataProviderBounds {
    pub count: Option<CountBound>,
    pub size: Option<SizeBound>,
}

Data bounds for election data.

Limits the data returned by DataProvider implementors, defined over two axis: count, defining the maximum number of elements returned, and size, defining the limit in size (bytes) of the SCALE encoded result.

None represents unlimited bounds in both count and size axis.

Fields

count: Option<CountBound>

size: Option<SizeBound>

Implementations

impl DataProviderBounds

pub fn count_exhausted(self, given_count: CountBound) -> bool

Returns true if given_count exhausts self.count.

pub fn size_exhausted(self, given_size: SizeBound) -> bool

Returns true if given_size exhausts self.size.

pub fn exhausted( self, given_size: Option<SizeBound>, given_count: Option<CountBound> ) -> bool

Returns true if given_size or given_count exhausts self.size or self_count, respectively.

pub fn max(self, bounds: DataProviderBounds) -> Self

Returns an instance of Self that is constructed by capping both the count and size fields. If self is None, overwrite it with the provided bounds.

Trait Implementations

impl Clone for DataProviderBounds

fn clone(&self) -> DataProviderBounds

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DataProviderBounds

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

Formats the value using the given formatter.

impl Default for DataProviderBounds

fn default() -> DataProviderBounds

Returns the “default value” for a type.

impl PartialEq for DataProviderBounds

fn eq(&self, other: &DataProviderBounds) -> 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.
