Module textarea 

Structs

ElementId

Stable, unique identifier for a text element. Monotonically increasing, never reused.

ElementKind

Opaque element kind tag. The textarea does not interpret this value; the host app defines constants like ElementKind(1) for pastes, ElementKind(2) for file references, etc.

InternalClipboard

In-memory clipboard — the default provider.

Selection

A byte-range selection in the buffer, created by mouse drag.

TextArea

TextAreaState

TextElement

An atomic text element embedded in the buffer.

TextElementEvent

An interaction with a TextElement, returned by TextArea::poll_element_event.

Enums

MouseAction

Result of processing a mouse event in the textarea.

TextElementEventKind

The kind of element interaction.

Traits

ClipboardProvider

Trait for clipboard access. The textarea calls this on copy/cut/paste.

Functions

is_undo_input

Whether key is the undo chord TextArea::input binds: lowercase ‘z’ with Ctrl or Cmd. Uppercase ‘Z’ (redo) is intentionally excluded, which keeps this guard disjoint from the redo arm regardless of order.
