Struct TopologyConfig 

pub struct TopologyConfig {
    pub assignments: Vec<MirrorAssignment>,
    pub buckets: Vec<BucketLogEntry>,
}

Mirror-to-machine assignment table from .yah/cloud/topology.toml.

Declares which logical mirror names are assigned to which machines. This is the source-canonical placement until yubaba raft observes it (per the migration tracker in the arch doc).

Fields

assignments: Vec<MirrorAssignment>

Mirror→machine assignments.

buckets: Vec<BucketLogEntry>

Declared buckets, logged by yah cloud bucket create. Source-canonical until yubaba raft observes actual placement.

Implementations

impl TopologyConfig

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

Load from a topology.toml file, returning Default when absent.

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

Persist to topology.toml, creating parent dirs if needed.

pub fn bucket_by_name(&self, name: &str) -> Option<&BucketLogEntry>

Find a declared bucket by name.

pub fn bucket_by_name_mut(&mut self, name: &str) -> Option<&mut BucketLogEntry>

Find a mutable declared bucket by name.

pub fn is_cross_machine_bucket(&self, name: &str) -> bool

Returns true if the bucket is declared as cross-machine (no owning machine).
