Top-level configuration for fast-cache-server.

Fields

bind_addr: String

Socket address the server should bind, for example 127.0.0.1:6380.

max_connections: usize

Maximum number of accepted client connections.

shard_count: usize

Number of storage shards to create. Must be a non-zero power of two.

max_memory_bytes: u64

Global memory budget in bytes. 0 disables memory-limit eviction.

eviction_policy: EvictionPolicy

Policy used when a memory limit is configured.

ttl_sweep_interval_ms: u64

Interval between TTL maintenance sweeps.

stats_interval_ms: u64

Interval between periodic stats reports.

tiers: TierConfig

Per-shard tier sizing.

cuda: CudaConfig

GPU-facing configuration values.

persistence: PersistenceConfig

WAL and snapshot configuration.

replication: ReplicationConfig

Native mutation-stream replication configuration.

Implementations

impl FastCacheConfig

pub fn default_shard_count() -> usize

Returns the default shard count for the current host.

pub fn load_from_path(path: &Path) -> Result<Self>

Loads and validates a TOML configuration file.

pub fn store_to_path(&self, path: &Path) -> Result<()>

Writes the configuration as pretty TOML, creating parent directories.

pub fn ensure_paths(&self) -> Result<()>

Creates directories required by the enabled persistence settings.

pub fn validate(&self) -> Result<()>

Validates cross-field constraints.

pub fn ttl_sweep_interval(&self) -> Duration

Returns the TTL sweep interval, clamped to at least 1 ms.

pub fn stats_interval(&self) -> Duration

Returns the stats interval, clamped to at least 250 ms.

pub fn per_shard_memory_limit_bytes(&self) -> Option<usize>

Returns the per-shard memory limit implied by max_memory_bytes.

pub fn snapshot_interval(&self) -> Duration

Returns the snapshot interval, clamped to at least 1 second.
