Struct ConfChange 

pub struct ConfChange {
    pub change_type: ConfChangeType,
    pub node_id: u64,
}

A configuration change for a Raft group.

Fields

change_type: ConfChangeType

node_id: u64

The node being added or removed.

Implementations

impl ConfChange

pub fn to_entry_data(&self) -> Vec<u8>

Serialize to bytes for a Raft log entry (prefixed with CONF_CHANGE_PREFIX).

pub fn from_entry_data(data: &[u8]) -> Option<Self>

Try to deserialize from a Raft log entry’s data bytes.

Returns None if the entry is not a configuration change (wrong prefix).

pub fn is_conf_change(data: &[u8]) -> bool

Check if a log entry’s data is a configuration change (without full deserialization).
