Enum ControlObjectKind 

pub enum ControlObjectKind {
    WalHead,
    WalFloor,
    MetadataRoot,
    CheckpointRecord,
    UploadSession,
}

Selects one independently versioned mutable control-object family.

See mutable control-object rules.

Variants

WalHead

Carries the sole live-visibility and writer-fencing authority.

WalFloor

Records the earliest sequence for which incremental history is retained.

MetadataRoot

Points to the best known materialized metadata manifest.

CheckpointRecord

Pins a manifest basis for a user or fork lifecycle.

UploadSession

Tracks staged content through upload completion or cleanup.

Implementations

impl ControlObjectKind

pub const ALL: [Self; 5]

Lists every registered control-object family in stable registry order.

pub const fn format_version(self) -> u32

Durable format version for this control object kind.

Versions are tracked per kind so one kind’s payload schema can make a breaking change without invalidating every other control object. Version 1 is a JSON envelope document carrying the current payload as a raw JSON fragment whose checksum covers its exact bytes.

pub const fn as_str(self) -> &'static str

Returns the frozen envelope discriminator for this control-object family.

pub fn parse(value: &str) -> Option<Self>

Parses a registered envelope discriminator, returning None for future families.
