Crate Boundaries

Good crate boundaries make the project easier to change.

forge-domain

Contains pure domain types.

Examples:

ProjectId
ContinuityId
EntityId
EntityKind
RelationshipKind
Visibility
Secret
ChronologyEvent
Mutation

Should avoid:

SQL
HTTP
Axum
Tonic
UI code
database clients

forge-application

Contains use cases.

Examples:

CreateProject
AddEntity
AddRelationship
RevealSecret
RecordContinuityEvent
AddCollaborator

Depends on:

forge-domain
forge-storage
forge-auth traits, if needed

forge-storage

Contains repository traits.

Example:

#![allow(unused)]
fn main() {
#[async_trait::async_trait]
pub trait ProjectRepository {
    async fn get_project(&self, id: ProjectId) -> Result<Option<Project>, StorageError>;
    async fn save_project(&self, project: &Project) -> Result<(), StorageError>;
}
}
