Struct Buttons 

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

Which of the non-primary buttons a node’s on_button claims: Buttons::SECONDARY, Buttons::MIDDLE and Buttons::OTHER (every button past the named three), or-ed together. A node declaring on_button claims Buttons::ALL unless it says otherwise. The primary button is never in it: that one presses, drags and clicks for every node.

The C ABI’s spelling is the same bits (KuiSpec.buttons: 1 secondary, 2 middle, 4 other), a zeroed field meaning all three; the schema’s is the names, "secondary middle".

Implementations

impl Buttons

pub const NONE: Self

Claims nothing: an on_button that hears no press.

pub const SECONDARY: Self

The context-menu button. Claimed, its press is the owner’s button event instead of a contextmenu event or the stock menu.

pub const MIDDLE: Self

pub const OTHER: Self

Every button past the named three (back, forward, thumb buttons).

pub const ALL: Self

pub fn contains(self, button: MouseButton) -> bool

Whether button is in the set. The primary button never is.

pub const fn bits(self) -> u32

As bits, the C ABI’s spelling: 1 secondary, 2 middle, 4 other.

pub fn from_bits(bits: u32) -> Self

From Buttons::bits; unknown bits are ignored. Zero is Buttons::NONE here: it is the C binding that reads a zeroed field as all three, being a field the host never set.

pub fn parse(names: &str) -> Self

From the schema’s spelling: names separated by spaces or commas — "middle", "secondary middle", "secondary, middle, other". A word that is none of the three is skipped, so a string of none of them claims nothing: a typo never takes the secondary button away from a context menu.
