Finalize Facilities

Required methods

`fn apply_finality( &self, operation: &mut ClientImportOperation<Block, B>, id: BlockId<Block>, justification: Option<Justification>, notify: bool ) -> Result<()>`[src]

Mark all blocks up to given as finalized in operation.

If justification is provided it is stored with the given finalized block (any other finalized blocks are left unjustified).

If the block being finalized is on a different fork from the current best block the finalized block is set as best, this might be slightly inaccurate (i.e. outdated). Usages that require determining an accurate best block should use SelectChain instead of the client.

`fn finalize_block( &self, id: BlockId<Block>, justification: Option<Justification>, notify: bool ) -> Result<()>`[src]

Finalize a block.

This will implicitly finalize all blocks up to it and fire finality notifications.

If the block being finalized is on a different fork from the current best block, the finalized block is set as best. This might be slightly inaccurate (i.e. outdated). Usages that require determining an accurate best block should use SelectChain instead of the client.

Pass a flag to indicate whether finality notifications should be propagated. This is usually tied to some synchronization state, where we don’t send notifications while performing major synchronization work.
