CollectNAInt

miniextendr_api::convert

Struct CollectNAInt

pub struct CollectNAInt<I>(pub I);

Expand description

Write an ExactSizeIterator of Option<i32> directly into an R integer vector with NA.

Like Collect, this is an iterator adapter and is exempt from the As* naming convention (see #871).

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<T, U> Into<U> for T
where U: From<T>,

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

impl<T> SizeHint for T
where T: ?Sized,

default fn lower_bound(&self) -> usize

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

Returns a lower bound on the number of elements this container-like item contains. For example, an array [u8; 12] could return any value between 0 and 12 inclusively as a correct implementation. Read more

default fn upper_bound(&self) -> Option<usize>

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

Returns an upper bound on the number of elements this container-like item contains if it can be determined, otherwise None. Read more

final fn size_hint(&self) -> (usize, Option<usize>)

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

Returns an estimate for the number of elements this container like type contains. Read more

impl<T, U> TryFrom<U> for T
where U: Into<T>,

type Error = Infallible

The type returned in the event of a conversion error.

fn try_from(value: U) -> Result<T, <T as TryFrom<U>>::Error>

Performs the conversion.

impl<T, U> TryInto<U> for T
where U: TryFrom<T>,

type Error = <U as TryFrom<T>>::Error

The type returned in the event of a conversion error.

fn try_into(self) -> Result<U, <U as TryFrom<T>>::Error>

Performs the conversion.

Layout§

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
