Struct SRefMut 

pub struct SRefMut<'o, T: StableType + AsFixedSizeBytes> { /* private fields */ }

Mutable reference to data stored in stable memory

See also SRef.

Lazy on reads - only loads and deserializes the data, when it gets accessed. Lazy on writes - only performs actual underlying data updates when Drop-ped. Useful when building your own stable data structure. Immutable and mutable access is provided by dereferencing.

T has to implement StableType and AsFixedSizeBytes.

Implementations

impl<'o, T: StableType + AsFixedSizeBytes> SRefMut<'o, T>

pub unsafe fn new(ptr: u64) -> Self

Creates mutable reference from raw pointer.

Safety

Make sure your raw pointer points to a valid location.
