Enum DropPosition 

pub enum DropPosition {
    Before(usize),
    After(usize),
    Inside(usize),
    Replace(usize),
    Append,
}

Where within a drop target the drop will occur.

Used by DropTarget::drop_position to communicate precise placement to the drop handler.

Variants

Before(usize)

Before the item at the given index.

After(usize)

After the item at the given index.

Inside(usize)

Inside the item at the given index (for tree-like targets).

Replace(usize)

Replace the item at the given index.

Append

Append to the end of the target’s items.

Implementations

impl DropPosition

pub fn index(&self) -> Option<usize>

Returns the index associated with this position, if any.

pub fn is_insertion(&self) -> bool

Returns true if this is an insertion position (Before or After).

pub fn from_list(y: u16, item_height: u16, item_count: usize) -> Self

Calculate a list drop position from a y coordinate within a list.

Divides each item’s height in half: the upper half maps to Before, the lower half maps to After.

Panics

Panics if item_height is zero.

Trait Implementations

impl Clone for DropPosition

fn clone(&self) -> DropPosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DropPosition

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

Formats the value using the given formatter.

impl PartialEq for DropPosition

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