Struct NamespaceOpts 

pub struct NamespaceOpts {
    pub path: Option<PathBuf>,
    pub shards: usize,
    pub mem_budget_mb: Option<usize>,
}

Commonly used items, re-exported for convenience.

This includes data size constants (KB, MB, GB), raw data types (RawBytes, RawKey, RawValue), and functions for managing the database environment (e.g., vsdb_flush, vsdb_configure). Creation-time options; persisted in the registry. Everything is defaulted — this struct exists for the advanced tier.

Fields

path: Option<PathBuf>

None ⇒ derived under {default_base}/__NAMESPACES__/, recorded as derived so the whole universe stays movable as one tree. Some ⇒ explicit root (e.g. a dir on another volume), stored absolute and pinned (Namespace::relocate to move). Rejected if it nests inside the default base dir or another registered namespace root (or vice versa).

shards: usize

Shard count, fixed at creation (routing is prefix % shards). Clamped to 1..=64.

mem_budget_mb: Option<usize>

Memory sizing input in MiB; None ⇒ 512 MiB. Cache/buffer floors and caps apply; this is not a hard RSS limit.
