Struct NrVec 

pub struct NrVec<T> { /* private fields */ }

A vector with a pointer, length, and capacity. This struct is #[repr(C)] and ABI-stable.

Owned values carry a producer-side drop callback so the receiving module never deallocates them with the wrong allocator. Borrowed foreign values use owned = 0 and are never freed by this type. Prefer NrBytes for ordinary borrowed input.

Implementations

impl NrVec<u8>

pub unsafe fn from_nr_bytes(bytes: NrBytes) -> Result<Self, NrViewError>

Copies an ABI byte view into an owned vector.

Safety

bytes must point to readable memory for its declared length.

pub fn from_string(s: String) -> Self

impl<T> NrVec<T>

pub fn from_vec(v: Vec<T>) -> Self

Takes ownership of a Rust vector without copying its allocation.

pub fn into_vec(self) -> Vec<T>

where T: Clone,

Copies the elements into a vector owned by the current module.

The source allocation is released by the allocator-specific callback supplied by the module that created this NrVec.

pub fn capacity(&self) -> usize

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn as_ptr(&self) -> *const T

pub fn as_mut_ptr(&mut self) -> *mut T

impl<T> NrVec<T>

pub fn iter(&self) -> Iter<'_, T>

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

Trait Implementations

impl<T: Clone> Clone for NrVec<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for NrVec<T>

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

Formats the value using the given formatter.

impl<T> Default for NrVec<T>

fn default() -> Self

Returns the “default value” for a type.

impl<T> Drop for NrVec<T>

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<'a, T> IntoIterator for &'a NrVec<T>

type Item = &'a T

The type of the elements being iterated over.

type IntoIter = Iter<'a, T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<T: Clone> IntoIterator for NrVec<T>

type Item = T

The type of the elements being iterated over.

type IntoIter = IntoIter<T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
