Enum StableShardActivationError 

pub enum StableShardActivationError {
    CannotShrink {
        current: u32,
        requested: u32,
    },
    ExceedsMax {
        requested: u32,
    },
    ModulusRoutingActive,
    NotMultiRaft,
}

Why stable shard activation was rejected.

Variants

CannotShrink

new_active must be strictly greater than the current active count.

Fields

current: u32

Current active virtual shards.

requested: u32

Requested active count.

ExceedsMax

new_active exceeds MAX_VIRTUAL_SHARDS.

Fields

requested: u32

Requested active count.

ModulusRoutingActive

Tier 1 modulus routing is active — use ShardRouter::expand_shard_count.

NotMultiRaft

Activation requires multi-Raft (raft_groups > 1).

impl Eq for StableShardActivationError

impl Error for StableShardActivationError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
