Enum ScrollbarPolicy 

pub enum ScrollbarPolicy {
    Always,
    Minimize,
    Collapse,
}

Behaviour of the scrollbar.

Variants

Always

Always renders the scrollbar recognizable as scrollbar.

Minimize

If the scrollbar is not needed, it will be rendered in a ‘minimized’ style.

If a min_symbol is set, the area for the scrollbar will be filled with the symbol. If a min_styleis set, the area for the scrollbar will be set to this style. If no min_symbol is set, this will just set the style.

The scrollbar is not needed, if max_offset == 0.

Collapse

If the scrollbar is not needed, no area is reserved for it. The widget will get the extra area.

If the scrollbar is rendered combined with a block, the block still might reserve the same space for itself.

Trait Implementations

impl Clone for ScrollbarPolicy

fn clone(&self) -> ScrollbarPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScrollbarPolicy

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

Formats the value using the given formatter.

impl Default for ScrollbarPolicy

fn default() -> ScrollbarPolicy

Returns the “default value” for a type.

impl PartialEq for ScrollbarPolicy

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