Struct Capabilities 

pub struct Capabilities(pub u64);

Typed wrapper around the raw capability bitfield from HelloAckFrame.

Obtained via NodeDb::capabilities(). Use the predicate methods to test for specific server features before calling the corresponding operations.

Example

let caps = Capabilities::from_raw(0x07); // streaming + graphrag + fts
assert!(caps.supports_streaming());
assert!(caps.supports_graphrag());
assert!(!caps.supports_crdt());

Tuple Fields

0: u64

Implementations

impl Capabilities

pub fn from_raw(bits: u64) -> Self

Create from a raw capability bitfield.

pub fn raw(self) -> u64

Returns the underlying raw bitfield.

pub fn supports_streaming(self) -> bool

Whether the server supports response streaming (partial-response chunking via ResponseStatus::Partial).

pub fn supports_graphrag(self) -> bool

Whether the server supports the GraphRagFusion opcode.

pub fn supports_fts(self) -> bool

Whether the server supports full-text search opcodes (TextSearch, HybridSearch).

pub fn supports_crdt(self) -> bool

Whether the server supports CRDT operations (CrdtRead, CrdtApply).

pub fn supports_spatial(self) -> bool

Whether the server supports spatial scan (SpatialScan).

pub fn supports_timeseries(self) -> bool

Whether the server supports timeseries operations (TimeseriesScan, TimeseriesIngest).

pub fn supports_columnar(self) -> bool

Whether the server supports columnar operations (ColumnarScan, ColumnarInsert).

pub fn has(self, bit: u64) -> bool

Test an arbitrary capability bit.

Trait Implementations

impl Clone for Capabilities

fn clone(&self) -> Capabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Capabilities

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

Formats the value using the given formatter.

impl Default for Capabilities

fn default() -> Capabilities

Returns the “default value” for a type.

impl PartialEq for Capabilities

fn eq(&self, other: &Capabilities) -> 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.
