Struct VmoStorage 

pub struct VmoStorage { /* private fields */ }

Userspace-only storage backed by a VMO (Virtual Memory Object).

Implementations

impl VmoStorage

pub const fn new() -> Self

Create a new, unallocated VmoStorage.

pub fn get_vmo(&self) -> Option<&Vmo>

Access the underlying VMO if allocated.

Trait Implementations

impl Debug for VmoStorage

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for VmoStorage

fn default() -> VmoStorage

Returns the “default value” for a type.

impl Drop for VmoStorage

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Storage for VmoStorage

const SUPPORTS_GROW: bool = true

True if this storage supports growing.

fn allocate(&mut self, size: usize) -> Result<(), Status>

Allocates at least size bytes of storage.

fn get_data(&self) -> &[usize]

Returns a read-only slice of usize words to the underlying storage.

fn get_data_mut(&mut self) -> &mut [usize]

Returns a mutable slice of usize words to the underlying storage.

fn grow(&mut self, size: usize) -> Result<(), Status>

Optionally grows the storage to at least size bytes.
