Struct IoLimits 

pub struct IoLimits { /* private fields */ }

Limits on storage and requests owned by one input driver.

This bounds retained payload capacities, stored range descriptors and the number of ranges handed to a source at once. It excludes caller-owned slices, allocator bookkeeping/transient reallocation, source caches, codec allocations and output. It is not a process-memory limit.

Zero is valid: no owned payload, range descriptors or reads, respectively. Borrowed resident input remains usable with all three limits set to zero.

Implementations

impl IoLimits

pub const fn new(input_bytes: usize, ranges: usize, in_flight: usize) -> Self

Construct finite limits. Requests are checked before allocation or I/O.

pub const fn unlimited() -> Self

Preserve the historical unbounded driver configuration.

pub const fn max_input_bytes(self) -> usize

Maximum retained driver-owned payload capacity.

pub const fn max_ranges(self) -> usize

Maximum range descriptors in a fetch plan (excluding codec-owned requests).

pub const fn max_in_flight(self) -> usize

Maximum ranges passed to a source in one batch.
