Trait BlockStoreProvider

pub trait BlockStoreProvider {
    type Reader<'a>: BlockStoreTransaction
       where Self: 'a;
    type ReaderWriter<'a>: BlockStoreTransaction
       where Self: 'a;

    // Required methods
    fn checkout_ro(&self) -> Result<Self::Reader<'_>, BlockStoreError>;
    fn checkout_rw(&mut self) -> Result<Self::ReaderWriter<'_>, BlockStoreError>;
}

A block store that supports read/write operations consistently.

Required Associated Types

type Reader<'a>: BlockStoreTransaction where Self: 'a

Reader alias.

type ReaderWriter<'a>: BlockStoreTransaction where Self: 'a

ReaderWriter alias.

Required Methods

fn checkout_ro(&self) -> Result<Self::Reader<'_>, BlockStoreError>

Check out read only handle.

fn checkout_rw(&mut self) -> Result<Self::ReaderWriter<'_>, BlockStoreError>

Check out read write handle.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
