Struct TaskStoreUsage 

#[non_exhaustive]
pub struct TaskStoreUsage {
    pub task_count: usize,
    pub retained_bytes: usize,
    pub reserved_bytes: usize,
}

Content-free resource gauges for MemoryTaskStore.

reserved_bytes is headroom held for replacing every live record with a small, fixed retention-limit failure. The aggregate quota applies to retained_bytes + reserved_bytes; the split lets operators distinguish actual stored payload from safety headroom without exposing task contents.

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.

task_count: usize

Number of task records physically retained, including tombstones.

retained_bytes: usize

Compact-JSON bytes currently charged to retained task payloads.

reserved_bytes: usize

Bytes reserved for bounded terminal retention failures.

Implementations

impl TaskStoreUsage

pub fn charged_bytes(self) -> usize

Aggregate bytes charged against TaskRetentionLimits::max_retained_bytes.

Snapshots returned by MemoryTaskStore::usage cannot overflow. This accessor saturates only if a caller manually mutates the public gauge fields into a value no store can produce.
