Implementations

impl ScrollFlags

pub const EMPTY: ScrollFlags

No bit set.

pub const BACK: ScrollFlags

Back, toward the start: up, or left in a left-to-right layout.

pub const FORWARD: ScrollFlags

Forward, toward the end: down, or right in a left-to-right layout.

pub const fn contains(self, other: ScrollFlags) -> 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.
