Enum CreateObjectMappings 

pub enum CreateObjectMappings {
    Block(NonZeroU64),
    Yes,
    No,
}

Whether to create object mappings.

Variants

Block(NonZeroU64)

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

impl CreateObjectMappings

pub fn is_enabled(&self) -> bool

Returns true if object mappings will be created from a past or future block.

pub fn is_enabled_for_block(&self, block: BlockNumber) -> bool

Does the supplied block number need object mappings?

Trait Implementations

impl Clone for CreateObjectMappings

fn clone(&self) -> CreateObjectMappings

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CreateObjectMappings

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CreateObjectMappings

fn default() -> CreateObjectMappings

Returns the “default value” for a type.

impl PartialEq for CreateObjectMappings

fn eq(&self, other: &CreateObjectMappings) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
