[+] Show declaration

pub struct ServiceFlags(_);

[−] Expand description

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].
