Enum Change 

pub enum Change {
    Revoked,
    Superseded {
        by: Token,
    },
    ExpirySet {
        expires_at: Option<Timestamp>,
    },
    CampaignSet {
        campaign: Option<String>,
    },
    LabelSet {
        key: String,
        value: String,
    },
    LabelUnset {
        key: String,
    },
}

A change to a manifest’s mutable sections. Lifecycle changes are CAS (C-9, checked at the store’s commit point); cosmetic changes are LWW by commit order.

Variants

Revoked

Lifecycle: withdraw the token (tombstone, cascades to children).

Superseded

Lifecycle: replace with a corrected token.

Fields

by: Token

The replacement token.

ExpirySet

Lifecycle: set or clear expiry.

Fields

expires_at: Option<Timestamp>

New expiry (None clears).

CampaignSet

Cosmetic: set or clear the campaign label.

Fields

campaign: Option<String>

New campaign (None clears).

LabelSet

Cosmetic: set one label.

Fields

key: String

Label key.

value: String

Label value.

LabelUnset

Cosmetic: remove one label.

Fields

key: String

Label key.

Implementations

impl Change

pub fn is_lifecycle(&self) -> bool

Lifecycle changes require CAS (expected_version); cosmetic ones are LWW. The split is normative (C-9, doc 02).

Trait Implementations

impl Clone for Change

fn clone(&self) -> Change

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Change

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Change

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Change

impl PartialEq for Change

fn eq(&self, other: &Change) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for Change

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
