Struct ForeignF64Buffer 

pub struct ForeignF64Buffer { /* private fields */ }

Foreign-backed f64 slice kept alive by an opaque owner.

Implementations

impl ForeignF64Buffer

pub unsafe fn new( owner: Arc<dyn ForeignBufferOwner>, ptr: *const f64, len: usize, ) -> Self

Construct from a validated pointer and length.

Safety

• ptr must be valid for reads of len f64 values for the lifetime of owner.
• The pointed-to memory must be properly aligned for f64.
• No mutable aliases may exist while this buffer (or clones) is live.

pub fn as_slice(&self) -> &[f64]

Borrow as a slice.

pub const fn len(&self) -> usize

Length.

pub const fn is_empty(&self) -> bool

Whether empty.

Trait Implementations

impl Clone for ForeignF64Buffer

fn clone(&self) -> ForeignF64Buffer

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ForeignF64Buffer

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

Formats the value using the given formatter.

impl Drop for ForeignF64Buffer

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.
