Struct ProposalView 

pub struct ProposalView { /* private fields */ }

A view captures point-time proposal set, representing on-chain proposed transaction pool, stored in the memory so that there is no need to fetch on hard disk, create by ProposalTable finalize method w_close and w_far define the closest and farthest on-chain distance between a transaction’s proposal and commitment.

Implementations

impl ProposalView

pub fn new( gap: HashSet<ProposalShortId>, set: HashSet<ProposalShortId>, ) -> ProposalView

Create new ProposalView

pub fn gap(&self) -> &HashSet<ProposalShortId>

Return proposals between w_close and tip

pub fn set(&self) -> &HashSet<ProposalShortId>

pub fn contains_proposed(&self, id: &ProposalShortId) -> bool

Returns true if the proposals set between w_close and w_far contains the id.

pub fn contains_gap(&self, id: &ProposalShortId) -> bool

Returns true if the proposals set between w_close and tip contains the id.
