Struct actix_storage::dev::StorageBuilder

pub struct StorageBuilder { /* fields omitted */ }

Builder struct for Storage

A provider can either implement ExpiryStore directly, or implement Store and rely on another provider to provide expiration capablities. The builder will polyfill a ExpiryStore by combining an Expiry and a Store itself.

If there is no Expiry set in either of the ways, it will result in runtime errors when calling methods which require that functionality.

Implementations

impl StorageBuilder

#[must_use = "Builder must be used by calling finish"]pub fn store(self, store: impl Store + 'static) -> Self

This method can be used to set a Store, the second call to this method will overwrite the store.

#[must_use = "Builder must be used by calling finish"]pub fn expiry(self, expiry: impl Expiry + 'static) -> Self

This method can be used to set a Expiry, the second call to this method will overwrite the expiry.

The expiry should work on the same storage as the provided store.

#[must_use = "Builder must be used by calling finish"]pub fn expiry_store<T>(self, expiry_store: T) -> Self where
    T: 'static + Store + Expiry + ExpiryStore, 

This method can be used to set an ExpiryStore directly, Its error to call expiry or store after calling this method.

#[must_use = "Builder must be used by calling finish"]pub fn format(self, format: Format) -> Self

This method can be used to set the format storage will use for serialization/deserialization, we will use default format if it is not called which can be None if there is no serde feature enabled.

pub fn finish(self) -> Storage

This method should be used after configuring the storage.

Panics

If there is no store provided either by calling expiry_store or store it will panic.
