Enum CreateObjectMappings

Source 
pub enum CreateObjectMappings {
    Block(NonZeroU32),
    Yes,
    No,
}
Expand description

Whether to create object mappings.

Variants§

§

Block(NonZeroU32)

Start creating object mappings from this block number.

This can be lower than the latest archived block, but must be greater than genesis.

The genesis block doesn’t have mappings, so starting mappings at genesis is pointless. The archiver will fail if it can’t get the data for this block, but snap sync doesn’t store the genesis data on disk. So avoiding genesis also avoids this error. https://github.com/paritytech/polkadot-sdk/issues/5366

§

Yes

Create object mappings as archiving is happening.

§

No

Don’t create object mappings.

Implementations§

pub fn is_enabled(&self) -> bool
