Calc(Calculation)

Calculated expression.

Implementations

impl Number

pub fn calc(&self, container: f32, view_width: f32, view_height: f32) -> f32

Evaluates this number to a concrete pixel value.

Percentages are calculated relative to container, viewport units relative to view_width and view_height.

pub fn as_dynamic(&self) -> Option<&Self>

Returns a reference to this number if it is dynamic.

Dynamic numbers depend on container size (percentages).

pub fn is_dynamic(&self) -> bool

Checks if this number is dynamic.

pub fn as_fixed(&self) -> Option<&Self>

Returns a reference to this number if it is fixed.

Fixed numbers don’t depend on container size.

pub fn is_fixed(&self) -> bool

Checks if this number is fixed.
