Struct Services 

pub struct Services(/* private fields */);

• This just serializes to its numeric value for serde, but a list of strings would be nicer.

Implementations

impl Services

pub const FULL_BLOCKS: Self

The node provides at least the latest [nimiq_primitives::policy::NUM_BLOCKS_VERIFICATION] as full blocks.

pub const HISTORY: Self

The node provides the full transaction history.

pub const ACCOUNTS_PROOF: Self

The node provides inclusion and exclusion proofs for accounts that are necessary to verify active accounts as well as accounts in all transactions it provided from its mempool.

However, if Services::ACCOUNTS_CHUNKS is not set, the node may occasionally not provide a proof if it decided to prune the account from local storage.

pub const ACCOUNTS_CHUNKS: Self

The node provides the full accounts tree in form of chunks. This implies that the client stores the full accounts tree.

pub const MEMPOOL: Self

The node tries to stay on sync with the network wide mempool and will provide access to it.

Nodes that do not have this flag set may occasionally announce transactions from their mempool and/or reply to mempool requests to announce locally crafted transactions.

pub const TRANSACTION_INDEX: Self

The node provides an index of transactions allowing it to find historic transactions by address or by hash. Only history nodes will have this flag set. Nodes that have this flag set may prune any part of their transaction index at their discretion, they do not claim completeness of their results either.

pub const VALIDATOR: Self

This node is configured as a validator, so it is interested for other validator nodes.

pub const PRE_GENESIS_TRANSACTIONS: Self

This node provides pre-genesis information.

Get a flags value with all bits unset.

The bitwise or (|) of the bits in self and other.

pub fn remove(&mut self, other: Self)

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in self, truncating the result.

impl Services

pub const fn iter(&self) -> Iter<Services>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

pub const fn iter_names(&self) -> IterNames<Services>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
