Enum InstallMemoryPoolsError 

pub enum InstallMemoryPoolsError {
    PoolsInUse {
        bytes_in_use: u64,
    },
    StreamUnavailable,
    Unsupported,
}

Why installing a dynamic pool layout did not take effect.

The layout itself was already valid — that is PoolConfigError, reported when the configuration is resolved. This is about the pools’ state at the moment of the swap.

Variants

PoolsInUse

The dynamic pools still hold live allocations, so the old layout was kept. A live slice carries its pool position, and swapping the pool list under it would leave that position pointing at a different pool.

Transient: retry once whatever holds them drains. A cleanup that does not clear it usually means a cache is holding slices (the metadata info cache) or a captured graph is pinning them.

Fields

bytes_in_use: u64

Bytes still live in the dynamic pools.

StreamUnavailable

The calling stream could not be resolved because it is already in an error state. The layout still applies to streams created afterwards; the underlying failure surfaces at the next flush or sync, as usual.

Unsupported

This server has no configurable dynamic pools. Permanent — unlike PoolsInUse, retrying will never succeed.
