Trait ChainItem

pub(crate) trait ChainItem {
    type Type;

    // Required method
    fn read(
        chain: Option<&Arc<Chain>>,
        db: &ZebraDb,
        height: Height,
    ) -> Option<Self::Type>;
}

Required Associated Types

type Type

Required Methods

fn read( chain: Option<&Arc<Chain>>, db: &ZebraDb, height: Height, ) -> Option<Self::Type>

Read the Type at height from the non-finalized chain or finalized db.

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.
