Struct CanaryServiceImpl

Source

pub struct CanaryServiceImpl { /* private fields */ }

Expand description

Adapter implementing canary shard generation and check logic.

Generates an (N+1)th canary shard that cannot participate in real Reed-Solomon reconstruction. The canary is embedded into the first cover that has sufficient capacity.

Implementations§

Source §

impl CanaryServiceImpl

Source

pub const fn new(shard_size: usize, total_shards: u8) -> Self

Create a new canary service with the given shard parameters.

Source

pub fn verify_canary(shard: &Shard, canary_id: Uuid) -> bool

Check whether a shard matches the canary marker for a given ID.
