Enum ArrayDescriptor 

pub enum ArrayDescriptor {
    P32,
    Q64,
}

Which of the two variable length array descriptors a column uses.

Variants

P32

P: a pair of 32-bit integers, so a heap of up to 2 GiB.

Q64

Q: a pair of 64-bit integers, for heaps beyond that.

Implementations

impl ArrayDescriptor

pub fn bytes_len(&self) -> usize

Width of the descriptor as stored in the row.

pub fn read(&self, bytes: &[u8]) -> Option<(usize, usize)>

Reads a descriptor: how many elements the array has, and its byte offset into the heap.

Returns None for a descriptor that is truncated, or that describes a negative count or offset.
