    // Required method
    fn scannable_block(
        &self,
        hash: [u8; 32],

}

Provides scannable blocks from an untrusted interface.

This provides some of its methods yet (contiguous_scannable_blocks || scannable_block_by_number) MUST be overriden, and the batch method SHOULD be overriden.

Required Methods

fn scannable_block( &self, hash: [u8; 32], ) -> impl Send + Future<Output = Result<UnvalidatedScannableBlock, InterfaceError>>

Get a ScannableBlock by its hash.

No validation is applied to the received block other than that it deserializes.

Provided Methods

fn contiguous_scannable_blocks( &self, range: RangeInclusive<usize>, ) -> impl Send + Future<Output = Result<Vec<UnvalidatedScannableBlock>, InterfaceError>>

Get a contiguous range of ScannableBlocks.

No validation is applied to the received blocks other than that they deserialize and have the expected amount of blocks returned.

fn scannable_block_by_number( &self, number: usize, ) -> impl Send + Future<Output = Result<UnvalidatedScannableBlock, InterfaceError>>

Get a ScannableBlock by its number.

No validation is applied to the received block other than that it deserializes.

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.
