Struct grin_p2p::types::Capabilities

pub struct Capabilities { /* fields omitted */ }

Options for what type of interaction a peer supports

Methods

impl Capabilities

pub const UNKNOWN: Capabilities

We don't know (yet) what the peer can do.

pub const HEADER_HIST: Capabilities

Can provide full history of headers back to genesis (for at least one arbitrary fork).

pub const TXHASHSET_HIST: Capabilities

Can provide block headers and the TxHashSet for some recent-enough height.

pub const PEER_LIST: Capabilities

Can provide a list of healthy peers

pub const FULL_NODE: Capabilities

All nodes right now are "full nodes". Some nodes internally may maintain longer block histories (archival_mode) but we do not advertise this to other nodes.

pub fn empty() -> Capabilities

Returns an empty set of flags.

pub fn all() -> Capabilities

Returns the set containing all flags.

pub fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<Capabilities>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub fn from_bits_truncate(bits: u32) -> Capabilities

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub fn intersects(&self, other: Capabilities) -> bool

Returns true if there are flags common to both self and other.

pub fn contains(&self, other: Capabilities) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: Capabilities)

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

pub fn toggle(&mut self, other: Capabilities)

Toggles the specified flags in-place.

pub fn set(&mut self, other: Capabilities, value: bool)

Inserts or removes the specified flags depending on the passed value.
