Struct WorkspaceLimits 

pub struct WorkspaceLimits {
    pub max_open: usize,
    pub idle_timeout_ms: u64,
}

How many databases a workspace keeps open, and for how long.

Fields

max_open: usize

Most databases held open at once. The least recently used is closed to make room. 0 is read as 1 — a pool that holds nothing would reopen on every call.

idle_timeout_ms: u64

How long a database may sit unused before Workspace::close_idle closes it. 0 disables the sweep, so handles stay until evicted.

This is not a memory knob, it is a liveness knob: an open writer holds the file’s exclusive lock, so nothing else on the machine can touch that database until the handle goes. A long-running server that never let go would make its databases permanently unreachable from the CLI.

Implementations

impl WorkspaceLimits

pub fn ceiling(&self) -> usize

The effective ceiling: at least one, never more than MAX_OPEN_CEILING. Clamped here, in one place, because max_open can arrive from a config file and neither end of the range is safe to trust.
