Function take

src/ore/src/pager.rs:243–248

Consumes handle, writing the entire payload into `dst` (cleared first), then reclaims storage. Swap fast path: single-chunk handle into empty `dst` swaps in place, no copy. Panics on I/O failure. Use [`try_take`] to surface the error.

(handle: Handle, dst: &mut Vec<u64>)

///
/// Panics on I/O failure. Use [`try_take`] to surface the error.
pub fn take(handle: Handle, dst: &mut Vec<u64>) {
    match &handle.inner {
        HandleInner::Swap(_) => swap::take_swap(handle, dst),
        HandleInner::File(_) => file::take_file(handle, dst),
    }
}

/// Fallible counterpart to [`take`]. On I/O error the handle is consumed and
/// `dst` may hold partial data; the scratch file is unlinked on inner drop.
