Enum BlockAttachment
pub enum BlockAttachment {
Canonical,
HistoricalFork,
}
Expand description
Re-export of the blockchain tree API. Represents what kind of block is being executed and validated.
This is required to:
- differentiate whether trie state updates should be cached.
- inform other
This is required because the state root check can only be performed if the targeted block can be traced back to the canonical head.
Variants§
Canonical
The block
is canonical or a descendant of the canonical head.
([head..(block.parent)*,block
])
HistoricalFork
The block can be traced back to an ancestor of the canonical head: a historical block, but this chain does not include the canonical head.
Implementations§
§impl BlockAttachment
impl BlockAttachment
pub const fn is_canonical(&self) -> bool
pub const fn is_canonical(&self) -> bool
Returns true
if the block is canonical or a descendant of the canonical head.
