[−][src]Struct heaparray::fat_array_ptr::FatPtrArray
Heap-allocated array, with array size stored with the pointer to the memory.
Examples
Creating an array:
use heaparray::fat_array_ptr::*; let len = 10; let array = FatPtrArray::new(len, |idx| idx + 3);
Indexing works as you would expect:
array[3] = 2; assert!(array[3] == 2);
Notably, you can take ownership of objects back from the container:
let mut array = FatPtrArray::new(10, |_| Vec::<u8>::new()); let replacement_object = Vec::new(); let owned_object = array.insert(0, replacement_object);
but you need to give the array a replacement object to fill its slot with.
Additionally, you can customize what information should be stored alongside the elements in
the array using the FatPtrArray::with_label
function:
struct MyLabel { pub even: usize, pub odd: usize, } let mut array = FatPtrArray::with_label( MyLabel { even: 0, odd: 0 }, 100, |label, index| { if index % 2 == 0 { label.even += 1; index } else { label.odd += 1; index } });
Invariants
This struct follows the same invariants as mentioned in crate::memory_block
,
and does not check for pointer validity; you should use this struct in the same
way you would use a raw array or slice.
