pub enum ScrollDirection {
    LeftToRight,
    RightToLeft,
    TopToBottom,
    BottomToTop,
}

Available on crate feature decode only.

Scroll direction (SWA scroll-direction field; 2-bit). Same wire mapping as PrintDirection.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

LeftToRight

Left to right.

RightToLeft

Right to left.

TopToBottom

Top to bottom.

BottomToTop

Bottom to top (default — NTSC roll-up).

Label per the project’s name() convention.

Trait Implementations

impl Clone for ScrollDirection

fn clone(&self) -> ScrollDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ScrollDirection

impl Debug for ScrollDirection

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

Formats the value using the given formatter.

impl Default for ScrollDirection

fn default() -> ScrollDirection

Returns the “default value” for a type.

impl Display for ScrollDirection

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

Formats the value using the given formatter.

impl Eq for ScrollDirection

impl PartialEq for ScrollDirection

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
