Struct PouchMeta 

pub struct PouchMeta {
    pub network_id: String,
    pub service_id: String,
    pub storage_bytes_bid: u64,
    pub storage_bytes_used: u64,
    pub joined_at: u64,
}

Persistent metadata for a Pouch storage bid.

Written when the Pouch service is first hatched and updated whenever a fragment is stored or removed.

Fields

network_id: String

Network this Pouch is participating in.

service_id: String

UUID of the Pouch service instance.

storage_bytes_bid: u64

Bytes offered to the network at bid time.

storage_bytes_used: u64

Bytes currently occupied by stored fragments.

joined_at: u64

Unix timestamp (seconds) when this Pouch joined.

Implementations

impl PouchMeta

pub fn new( network_id: String, service_id: String, storage_bytes_bid: u64, ) -> Self

Create a new meta record with storage_bytes_used = 0.

pub fn available_bytes(&self) -> u64

Bytes still available for new fragments.

pub fn has_capacity(&self, bytes: u64) -> bool

Whether the Pouch can accept bytes more data.

pub fn load(path: &Path) -> BpResult<Self>

Load from a meta.json file.

pub fn save(&self, path: &Path) -> BpResult<()>

Persist to a meta.json file (creates or overwrites).
