Struct NodeCapabilities 

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

Capability flags for Peat nodes.

These flags are announced during handshake so peers know what features each node supports.

Implementations

impl NodeCapabilities

pub const PERSISTENT_STORAGE: u16 = 0x0001

Can persist data across restarts.

pub const RELAY_CAPABLE: u16 = 0x0002

Can forward messages for multi-hop routing.

Supports full Automerge documents.

pub const PRIMITIVE_CRDT: u16 = 0x0008

Supports primitive CRDTs (LWW, counters, sets).

pub const BLOB_STORAGE: u16 = 0x0010

Can store and serve blobs.

pub const HISTORY_QUERY: u16 = 0x0020

Has sensor inputs.

pub const DISPLAY_OUTPUT: u16 = 0x0100

Has display output.

pub const ACTUATION: u16 = 0x0200

Has actuation capability (motors, etc.).

pub const fn empty() -> Self

Create empty capabilities.

pub const fn all() -> Self

Create capabilities with all flags set.

pub const fn lite() -> Self

Create typical Peat-Lite capabilities.

pub const fn full() -> Self

Create typical Peat-Full capabilities.

pub const fn from_bits(bits: u16) -> Self

Create new capabilities from raw bits.

pub const fn bits(&self) -> u16

Get raw bits.

pub const fn has(&self, cap: u16) -> bool

Check if a capability is set.

pub fn set(&mut self, cap: u16)

Set a capability.

pub fn clear(&mut self, cap: u16)

Clear a capability.

pub const fn intersection(&self, other: &Self) -> Self

Get intersection of capabilities (what both nodes support).

pub const fn can_sync_with(&self, other: &Self) -> bool

Check if this node can sync CRDTs with another.

pub fn encode(&self) -> [u8; 2]

Encode to 2 bytes (little-endian).

pub fn decode(bytes: [u8; 2]) -> Self

Decode from 2 bytes (little-endian).

Trait Implementations

impl Clone for NodeCapabilities

fn clone(&self) -> NodeCapabilities

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NodeCapabilities

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for NodeCapabilities

fn default() -> NodeCapabilities

Returns the “default value” for a type.

impl Display for NodeCapabilities

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for NodeCapabilities

fn eq(&self, other: &NodeCapabilities) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
