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

Performs copy-assignment from source.

impl Default for ImageScaleFilter

fn default() -> Self

Returns the "default value" for a type.

impl PartialOrd<ImageScaleFilter> for ImageScaleFilter

fn partial_cmp(&self, other: &ImageScaleFilter) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

#[must_use] fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.
