Struct DfSnapshot 

#[non_exhaustive]
pub struct DfSnapshot {
    pub storage_used: usize,
    pub storage_quota: Option<usize>,
    pub memory_used: usize,
    pub memory_quota: usize,
    pub worlds: usize,
}

Aggregate storage/memory snapshot.

Returned by crate::Engine::df. Quotas of 0/None mean “unlimited”; adapters should render that string for operator-facing output.

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.

storage_used: usize

Bytes used by durable bodies (SQLite-backed worlds).

storage_quota: Option<usize>

Configured durable quota, or None if unlimited.

memory_used: usize

Bytes used by in-memory bodies.

memory_quota: usize

Configured memory cap. 0 means unlimited.

worlds: usize

Total live worlds (durable + in-memory).
