Trait for storing and retrieving schema snapshots

Implementations can store snapshots in:

  • File system
  • Database
  • Version control
  • In-memory (for testing)

Required Methods§

Source

fn store<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, tenant: &'life1 TenantContext, snapshot: &'life2 SchemaSnapshot, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Store a snapshot for a tenant

Source

fn get_latest<'life0, 'life1, 'async_trait>( &'life0 self, tenant: &'life1 TenantContext, ) -> Pin<Box<dyn Future<Output = Result<Option<SchemaSnapshot>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Retrieve the latest snapshot for a tenant

Source

fn get_by_hash<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, tenant: &'life1 TenantContext, version_hash: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<Option<SchemaSnapshot>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Retrieve a specific snapshot by version hash

Source

fn list<'life0, 'life1, 'async_trait>( &'life0 self, tenant: &'life1 TenantContext, ) -> Pin<Box<dyn Future<Output = Result<Vec<SchemaSnapshot>>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

List all snapshots for a tenant (ordered by creation time, newest first)

Source

fn compare<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, tenant: &'life1 TenantContext, hash_a: &'life2 str, hash_b: &'life3 str, ) -> Pin<Box<dyn Future<Output = Result<SchemaDiff>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Compare two snapshots and return their version hashes

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
