CellCustody

reth_network_api::custody

Struct CellCustody 

Source 
pub struct CellCustody { /* private fields */ }
Expand description

Shared blob cell custody bitmap for EIP-8070 sparse blobpool sampling.

This stores the latest custodyColumns value received from engine_forkchoiceUpdatedV4, so network components can align blob cell sampling with the consensus client’s custody set. The value is a lightweight hint for sampling decisions, not a consensus-critical guard.

Implementations§

Source§

impl CellCustody

Source

pub fn get(&self) -> B128

Returns the currently configured blob cell custody bitmap.

Reads are intentionally cheap and eventually consistent. Concurrent custom-to-custom updates may briefly expose an in-flight bitmap, which is acceptable because custody is only used to steer future sampling requests.

Source

pub fn set(&self, custody_columns: B128)

Updates the blob cell custody bitmap.

Source

pub fn set_from_engine_api(&self, custody_columns: B128)

Updates the custody bitmap from the Engine API’s little-endian bitvector encoding.
