Enum Scaling 

pub enum Scaling {
    Min,
    Max,
    Exact(u16, u16),
}

Variants

Min

The QR code will be scaled to at least the size of the widget.

Note that this usually results in a QR code that is larger than the widget, which is not ideal.

Max

The QR code will be scaled to be at most the size of the widget.

Note that this may result in a QR code which is scaled more horizontally or vertically than the other, which may not be ideal.

Exact(u16, u16)

The QR code will be scaled so each pixel is the size of the given dimensions.

The minimum dimensions are 1x1 (width x height).

Trait Implementations

impl Clone for Scaling

fn clone(&self) -> Scaling

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Scaling

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

Formats the value using the given formatter.

impl Default for Scaling

fn default() -> Scaling

Returns the “default value” for a type.

impl PartialEq for Scaling

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

impl Copy for Scaling

impl Eq for Scaling

impl StructuralPartialEq for Scaling
