Enum TicketChange 

pub enum TicketChange {
    Priority {
        old: String,
        new: String,
    },
    Status {
        old: String,
        new: String,
    },
    Assignee {
        old: String,
        new: String,
    },
    Version {
        old: String,
        new: String,
    },
    DoneRatio {
        old: String,
        new: String,
    },
}

Represents a single field change detected between two versions of a LinkedTicket.

Design

This enum is the only place in the codebase where “which fields are trackable” is declared. Adding a new tracked field (e.g. Sprint, DoneRatio) only requires:

1. Adding a variant here.
2. Adding a match arm in LinkedTicket::diff.
3. Handling the new variant in the orchestrator’s notification dispatch.

The orchestrator (gitlab-tracker) and notification plugin (gitlab-tracker-notify) never need to know about field names directly — they only receive TicketChange values. This satisfies OCP: providers (Redmine, Jira, …) and consumers (app, notify) are decoupled from the field enumeration.

Variants

Priority

The priority label changed (e.g. “Normal” → “High”).

Fields

old: String

new: String

Status

The status label changed (e.g. “In Progress” → “Resolved”).

Fields

old: String

new: String

Assignee

The assignee changed (e.g. “Alice” → “Bob”, or “Unassigned” when empty).

Fields

old: String

new: String

Version

The target version/release changed (e.g. “v1.2” → “v1.3”, or “None” when unset).

Fields

old: String

new: String

DoneRatio

The completion percentage changed (0–100). Fires on both increase and decrease. old and new are formatted as “N%” strings for display consistency.

Fields

old: String

new: String

Implementations
