Struct StorageConfig 

pub struct StorageConfig {
    pub enabled: bool,
    pub verify_on_read: bool,
    pub db_size_gb: usize,
    pub disk_reserve_mb: u64,
}

Storage configuration for chunk persistence.

Controls how chunks are stored, including:

• Whether storage is enabled
• Content verification on read
• Database size limits (auto-scales with available disk by default)

Fields

enabled: bool

Enable chunk storage. Default: true

verify_on_read: bool

Verify content hash matches address on read. Default: true

db_size_gb: usize

Explicit LMDB database size cap in GiB.

When set to 0 (default), the map size is computed automatically from available disk space at startup and grows on demand when the operator adds storage. Set a non-zero value to impose a hard cap.

disk_reserve_mb: u64

Minimum free disk space (in MiB) to preserve on the storage partition.

Writes are refused when available space drops below this threshold, preventing the node from filling the disk completely. Default: 500 MiB.
