Struct frame_election_provider_support::bounds::DataProviderBounds

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

Expand description

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.
