One text-editing request addressed to entity’s crate::text_model::TextBuffer.

Producers write into a bevy_ecs::message::Messages queue; the single [lumen_text_edit::text_apply_edits] system drains them.

Variants

Insert

Insert text at at.

Fields

entity: Entity

Target editable.

at: TextPos

Resolved insertion position.

text: Arc<str>

Inserted bytes (Arc’d so producers don’t always allocate).

Delete

Delete the byte range.

Fields

entity: Entity

Target editable.

range: Range<usize>

Range to delete, in bytes.

Replace

Replace range with text (IME’s replacementStart/Length).

Fields

entity: Entity

Target editable.

range: Range<usize>

Range to replace, in bytes.

text: Arc<str>

Replacement bytes.

MoveCursor

Move the cursor.

Fields

entity: Entity

Target editable.

motion: CursorMotion

Motion axis.

mode: MoveMode

Selection modifier.

Select

Set selection range (in bytes).

Fields

entity: Entity

Target editable.

range: Range<usize>

Range of bytes to select.

SetCursor

Set cursor to an explicit position (collapses selection).

Fields

entity: Entity

Target editable.

pos: TextPos

New cursor position.

ExtendSelection

Move the selection head to pos while keeping the current anchor (Shift+click, pointer drag). Unlike Self::Select the anchor side is preserved, so repeated extends pivot around the same fixed end regardless of direction.

Fields

entity: Entity

Target editable.

pos: TextPos

New selection head.

SelectAll

Select all.

Fields

entity: Entity

Target editable.

Undo

Pop one entry off the undo stack.

Fields

entity: Entity

Target editable.

Redo

Re-apply the next redo entry.

Fields

entity: Entity

Target editable.

ImeBegin

Begin an IME composition (no-op if already active).

Fields

entity: Entity

Target editable.

ImeUpdate

Update the IME preedit.

Fields

entity: Entity

Target editable.

text: Arc<str>

New preedit string.

caret_in_preedit: usize

Caret byte offset inside text.

ImeCommit

Commit the IME preedit; replaces replace_range with text if replace_range is Some, otherwise inserts text at the cursor.

Fields

entity: Entity

Target editable.

text: Arc<str>

Final text.

replace_range: Option<Range<usize>>

Optional IME-requested replacement range (W3.5).

ImeCancel

Cancel any active IME preedit without committing.

Fields

entity: Entity

Target editable.
