Struct StorageInstance 

pub struct StorageInstance;

Module-level constructor surface for the supported backends.

Originally a 3-variant enum (Memory | Redis | Postgres) with a 350-line hand-written match-based dispatch implementing every Storage trait method. With the trait split into sub-traits and a blanket impl<T> Storage for T where T: ..., the enum + dispatch became pure boilerplate. Replaced with a unit struct whose associated functions return Arc<dyn Storage> directly — every backend type already satisfies Storage via the blanket impl, so no per-backend dispatch is needed.

Existing call sites (StorageInstance::memory(), StorageInstance::redis(cfg).await, etc.) keep their syntax; what changes is that those constructors now return Arc<dyn Storage> rather than an enum value the caller has to wrap in Arc::new.

Implementations

impl StorageInstance

pub async fn from_config( config: StorageConfig, ) -> Result<Arc<dyn Storage>, StorageError>

Create a storage instance from configuration.

Examples

use qml_rs::storage::{StorageInstance, StorageConfig, MemoryConfig};

let config = StorageConfig::Memory(MemoryConfig::default());
let storage = StorageInstance::from_config(config).await.unwrap();

pub fn memory() -> Arc<dyn Storage>

Create a memory storage instance with default configuration.

Examples

use qml_rs::storage::StorageInstance;

let storage = StorageInstance::memory();

pub fn memory_with_config(config: MemoryConfig) -> Arc<dyn Storage>

Create a memory storage instance with custom configuration.
