Enum BlockSource

Source 
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§

Source§

impl BlockSource

Source

pub const fn is_pending(&self) -> bool

Returns true if the block source is Pending or Any.

Source

pub const fn is_canonical(&self) -> bool

Returns true if the block source is Canonical or Any.
