Struct ShuffleTopologyFence 

Source 
pub struct ShuffleTopologyFence { /* private fields */ }
Expand description

Exact logical topology and catalog digest, independent of assignment and recovery counters. Installing this transport fence is a trusted control-path action, not an output or Release permit.

Implementations§

Source§

impl ShuffleTopologyFence

Source

pub fn new(version: u64, manifest_sha256: [u8; 32]) -> Result<Self>

Construct a nonzero version and nonzero manifest digest.

§Errors

Rejects reserved zero identities.

Source

pub const fn version(self) -> u64

Logical topology version, never an assignment, recovery or serialization version.

Source

pub const fn manifest_sha256(self) -> [u8; 32]

Exact content identity of the installed catalog.

Source

pub fn from_manifest( version: TopologyVersion, manifest: &CatalogManifestRef, ) -> Result<Self>

Derive a fence from a validated catalog reference on the control path.

§Errors

Rejects malformed references and reserved identities.
