Struct bitcoin::network::constants::ServiceFlags

pub struct ServiceFlags(_);

Flags to indicate which network services a node supports.

Methods

impl ServiceFlags

pub const NONE: ServiceFlags

NONE means no services supported.

pub const NETWORK: ServiceFlags

NETWORK means that the node is capable of serving the complete block chain. It is currently set by all Bitcoin Core non pruned nodes, and is unset by SPV clients or other light clients.

pub const GETUTXO: ServiceFlags

GETUTXO means the node is capable of responding to the getutxo protocol request. Bitcoin Core does not support this but a patch set called Bitcoin XT does. See BIP 64 for details on how this is implemented.

pub const BLOOM: ServiceFlags

BLOOM means the node is capable and willing to handle bloom-filtered connections. Bitcoin Core nodes used to support this by default, without advertising this bit, but no longer do as of protocol version 70011 (= NO_BLOOM_VERSION)

pub const WITNESS: ServiceFlags

WITNESS indicates that a node can be asked for blocks and transactions including witness data.

pub const COMPACT_FILTERS: ServiceFlags

COMPACT_FILTERS means the node will service basic block filter requests. See BIP157 and BIP158 for details on how this is implemented.

pub const NETWORK_LIMITED: ServiceFlags

NETWORK_LIMITED means the same as NODE_NETWORK with the limitation of only serving the last 288 (2 day) blocks. See BIP159 for details on how this is implemented.

pub fn add(&mut self, other: ServiceFlags) -> ServiceFlags

Add [ServiceFlags] together.

Returns itself.

pub fn remove(&mut self, other: ServiceFlags) -> ServiceFlags

Remove [ServiceFlags] from this.

Returns itself.

pub fn has(self, flags: ServiceFlags) -> bool

Check whether [ServiceFlags] are included in this one.

pub fn as_u64(self) -> u64

Get the integer representation of this [ServiceFlags].
