Trait StorageProvider 

pub trait StorageProvider {
    // Required methods
    fn status(&self) -> StorageStatus;
    fn health(&self) -> StorageHealth;
    fn open(&mut self) -> StorageResult<()>;

}

Storage provider contract.

Required Methods

fn status(&self) -> StorageStatus

Returns coarse provider availability.

fn health(&self) -> StorageHealth

Returns a current provider health snapshot.

fn open(&mut self) -> StorageResult<()>

Opens and validates provider resources.

fn close(&mut self) -> StorageResult<()>

Closes provider resources.

fn begin_transaction(&mut self) -> StorageResult<Box<dyn Transaction>>

Begins a real unit of work or fails explicitly when unsupported.

fn list_backups(&self) -> Vec<BackupDescriptor>

Lists provider-owned backups.

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