Trait ComputeStorage 

pub trait ComputeStorage: Send {
    type Resource: Send;

    // Required methods
    fn alignment(&self) -> usize;
    fn get(&mut self, handle: &StorageHandle) -> Result<Self::Resource, IoError>;
    fn alloc(&mut self, size: u64) -> Result<StorageHandle, IoError>;
    fn dealloc(&mut self, id: StorageId);
    fn flush(&mut self);
}

Storage types are responsible for allocating and deallocating memory.

Required Associated Types

type Resource: Send

The resource associated type determines the way data is implemented and how it can be accessed by kernels.

Required Methods

fn alignment(&self) -> usize

The alignment memory is allocated with in this storage.

fn get(&mut self, handle: &StorageHandle) -> Result<Self::Resource, IoError>

Returns the underlying resource for a specified storage handle.

Errors

IoError::StorageHandleNotFound when this storage holds no allocation for the handle’s id — a handle that outlived its allocation, or one whose id a deallocation retired.

fn alloc(&mut self, size: u64) -> Result<StorageHandle, IoError>

Allocates size units of memory and returns a handle to it

fn dealloc(&mut self, id: StorageId)

Deallocates the memory pointed by the given storage id.

These deallocations might need to be flushed with Self::flush.

fn flush(&mut self)

Flush deallocations when required.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
