Struct ArenaCfg 

pub struct ArenaCfg {
    pub shards: usize,
    pub max_bytes: usize,
    pub mode: ShardMode,
}

Arena configuration.

Stored verbatim in snapshots later, so everything that affects byte interpretation lives here.

Fields

shards: usize

Number of shards; must be a non-zero power of two.

max_bytes: usize

Hard ceiling for the byte pool; exceeding it fails with Error::CapacityExceeded instead of growing.

mode: ShardMode

Key-to-shard mapping mode.

Implementations

impl ArenaCfg

pub const fn new(shards: usize, mode: ShardMode) -> Self

Creates a config with the given shard count and mode, and no byte limit (max_bytes = usize::MAX).

pub const fn with_max_bytes(self, max_bytes: usize) -> Self

Returns the config with max_bytes replaced.
