Struct InMemoryDataSource 

pub struct InMemoryDataSource { /* private fields */ }

An in-memory DataSource used as the default backing store.

Rows are keyed by model name; each row is a JSON object. This is a real, fully-functional store (create/read/update/delete, search, filter, ordering and pagination) — just not a persistent one.

Implementations

impl InMemoryDataSource

pub fn new() -> Self

Create an empty store.

pub fn seed(&self, model_name: impl Into<String>, row: Value)

Seed a row for a model (test/setup helper). The row must be a JSON object; a primary key is generated if absent.

pub fn len(&self, model_name: &str) -> usize

Number of rows currently stored for a model.

Trait Implementations

impl DataSource for InMemoryDataSource

fn list<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, model: &'life1 ModelDefinition, query: &'life2 DataQuery, ) -> Pin<Box<dyn Future<Output = DataPage> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Fetch a page of rows for a list view.

fn get<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, model: &'life1 ModelDefinition, id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Option<Value>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Fetch a single record by primary-key value.

fn count<'life0, 'life1, 'async_trait>( &'life0 self, model: &'life1 ModelDefinition, ) -> Pin<Box<dyn Future<Output = usize> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Total number of records for a model (used by the dashboard summaries).

fn create<'life0, 'life1, 'async_trait>( &'life0 self, model: &'life1 ModelDefinition, data: Value, ) -> Pin<Box<dyn Future<Output = Result<String, AdminError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Create a record, returning its primary-key value.

fn update<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, model: &'life1 ModelDefinition, id: &'life2 str, data: Value, ) -> Pin<Box<dyn Future<Output = Result<(), AdminError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Update an existing record.

fn delete<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, model: &'life1 ModelDefinition, id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<(), AdminError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Delete a record.

impl Default for InMemoryDataSource

fn default() -> InMemoryDataSource

Returns the “default value” for a type.
