Trait freya::prelude::Storage

pub trait Storage<Data = ()>: AnyStorage + 'static {
    // Required methods
    fn try_read(
        &'static self,
        at: GenerationalRefBorrowInfo
    ) -> Result<Self::Ref<Data>, BorrowError>;

    ) -> Result<Self::Mut<Data>, BorrowMutError>;
    fn set(&'static self, value: Data);
}

A trait for a storage backing type. (RefCell, RwLock, etc.)

Required Methods

fn try_read( &'static self, at: GenerationalRefBorrowInfo ) -> Result<Self::Ref<Data>, BorrowError>

Try to read the value. Returns None if the value is no longer valid.

fn try_write( &'static self, at: GenerationalRefMutBorrowInfo ) -> Result<Self::Mut<Data>, BorrowMutError>

Try to write the value. Returns None if the value is no longer valid.

fn set(&'static self, value: Data)

Set the value
