Struct to manage an array of resources of type af_indexer_t(ArrayFire C struct)
While sharing an Indexer object with other threads, just move it across threads. At the moment, one cannot share borrowed references across threads.
Given below are examples illustrating correct and incorrect usage of Indexer struct.
Correct Usageuse arrayfire::{Array, Dim4, randu, index_gen, Indexer};
let dims = Dim4::new(&[1, 3, 1, 1]);
let indices = [1u8, 0, 1];
let idx = Array::new(&indices, dims);
let values = [2.0f32, 5.0, 6.0];
let arr = Array::new(&values, dims);
let mut idxr = Indexer::default();
idxr.set_index(&idx, 0, None);
index_gen(&arr, idxr); Incorrect Usage
ⓘThis example is not tested
idxr.set_index(&Array::new(&[1, 0, 1], dims), 0, None);
error: borrowed value does not live long enough

16 | idxr.set_index(&Array::new(&[1, 0, 1], dims), 0, None);
| ---------------------------- ^ temporary value dropped here while still borrowed

| temporary value created here

| - temporary value needs to live until here

= note: consider using a `let` binding to increase its lifetime
impl<'object> Indexer<'object>[src] pub fn new() -> Self[src] 👎
Deprecated since 3.7.0:
Use Indexer::default() instead
Create a new Indexer object and set the dimension specific index objects later
pub fn set_index<'s, T>(
&'s mut self,
idx: &'object T,
dim: u32,
is_batch: Option<bool>
) where
T: Indexable + 'object, [src]
Set either Array or Seq to index an Array along idx dimension
pub fn len(&self) -> usize[src]
Get number of indexing objects set
pub fn is_empty(&self) -> bool[src]
Check if any indexing objects are set
pub unsafe fn get(&self) -> af_index_t[src]
Get native(ArrayFire) resource handle
