Struct WhitelistMapper

pub struct WhitelistMapper<SA, T, A = CurrentStorage>
where
    SA: StorageMapperApi,
    A: StorageAddress<SA>,
    T: NestedEncode + 'static,
{ /* private fields */ }

A non-iterable whitelist mapper. Very efficient for storing a whitelist, as each item requires only one storage key. If you need to iterate over the keys, use UnorderedSetMapper or SetMapper instead.

Implementations

where SA: StorageMapperApi, T: TopDecode + TopEncode + NestedEncode + 'static,

pub fn contains(&self, item: &T) -> bool

pub fn require_whitelisted(&self, item: &T)

impl<SA, T> WhitelistMapper<SA, T, CurrentStorage>

where SA: StorageMapperApi, T: TopDecode + TopEncode + NestedEncode + 'static,

pub fn contains(&self, item: &T) -> bool

pub fn require_whitelisted(&self, item: &T)

pub fn add(&self, item: &T)

pub fn remove(&self, item: &T)
