Enum BlockSource
pub enum BlockSource {
Any,
Pending,
Canonical,
}
Expand description
A helper enum that represents the origin of the requested block.
This helper type’s sole purpose is to give the caller more control over from where blocks can be fetched.
Variants§
Any
Check all available sources.
Note: it’s expected that looking up pending blocks is faster than looking up blocks in the database so this prioritizes Pending > Database.
Pending
The block was fetched from the pending block source, the blockchain tree that buffers blocks that are not yet part of the canonical chain.
Canonical
The block must be part of the canonical chain.
Implementations§
§impl BlockSource
impl BlockSource
pub const fn is_pending(&self) -> bool
pub const fn is_pending(&self) -> bool
Returns true
if the block source is Pending
or Any
.
pub const fn is_canonical(&self) -> bool
pub const fn is_canonical(&self) -> bool
Returns true
if the block source is Canonical
or Any
.
