Struct DriveOptions 

#[non_exhaustive]
pub struct DriveOptions {
    pub max_gap: u64,
    pub read_size: usize,
    pub limits: IoLimits,
    pub work_quota: WorkQuota,
}

Tuning for the drivers.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

max_gap: u64

Requested ranges closer than this are merged into one read (HTTP: 16–64 KiB).

read_size: usize

Bytes read per round for a sequential request, on top of the decoder’s minimum.

limits: IoLimits

Admission for driver-owned input. Defaults to historical unlimited behavior.

work_quota: WorkQuota

Scheduling quota for async cursors and compute batches, independent of output draining.

Implementations

impl DriveOptions

pub const fn new(max_gap: u64, read_size: usize) -> Self

Options with the given coalescing gap and sequential read size.

pub const fn with_limits(self, limits: IoLimits) -> Self

Apply input admission to synchronous and asynchronous drivers alike.

pub const fn with_work_quota(self, quota: WorkQuota) -> Self

Bound uninterrupted async work without coupling it to destination reads.
