Struct Capabilities 

pub struct Capabilities(pub u32);

What an agent implements, advertised in its hello as a u32 bitmask. The host refuses a request whose method needs a capability the agent did not advertise (crate::message::Method::required_capability).

Direct text setting: text_set.

pub const BOUNDS: Capabilities

Nodes’ bounds read again past the platform’s node cache: bounds.

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

Whether every bit of other is set in self.

pub const fn is_empty(self) -> bool

Whether no bit is set.

pub fn names(self) -> impl Iterator<Item = &'static str>

The names of the bits set in self that this protocol version defines, lowest bit first.

impl Capabilities

pub const NONE: Capabilities = Capabilities::EMPTY

The empty set.

pub fn label(self) -> String
