Struct QueryCache 

Source 
pub struct QueryCache<'s, 'k, K, V>
where
    for<'a> &'a K: Debug + PartialEq + Eq + PrimaryKey<'a>,
    K: Clone + Debug + PartialEq + Eq,
    V: Clone + Serialize + DeserializeOwned,
{ /* private fields */ }
Expand description

A cache which stores values in memory to avoid repeated disk reads/writes. Values are accessed through a raw query to another contracts storage.

Blanket Implementations§

Source§

impl<T> Any for T
where T: 'static + ?Sized,

Source§

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more
Source§

impl<U> As for U

Source§

fn as_<T>(self) -> T
where T: CastFrom<U>,

Casts self to type T. The semantics of numeric casting with the as operator are followed, so <T as As>::as_::<U> can be used in the same way as T as U for numeric conversions. Read more
Source§

impl<T> Borrow<T> for T
where T: ?Sized,

Source§

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more
Source§

impl<T> BorrowMut<T> for T
where T: ?Sized,

Source§

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more
Source§

impl<T> From<T> for T

Source§

fn from(t: T) -> T

Returns the argument unchanged.

Source§

impl<T, U> Into<U> for T
where U: From<T>,

Source§

fn into(self) -> U

impl<T> Same for T

Source§

type Output = T

Should always be Self
