}

Debug snapshot for the wasm textarea IME bridge (ADR 0180).

This is intended for diagnostics/harness views and is not a normative contract surface.

Fields

enabled: bool

composing: bool

suppress_next_input: bool

textarea_has_focus: Option<bool>

Whether the hidden textarea is currently the document’s active element (focused).

This is best-effort and intended for diagnosing browser “user activation” restrictions where focus() calls can be ignored.

active_element_tag: Option<String>

Tag name of document.activeElement when available (e.g. "TEXTAREA", "CANVAS").

position_mode: Option<String>

Where the hidden textarea is positioned.

This is intentionally stringly-typed to keep the snapshot portable across runners. Expected values: "absolute", "fixed", or None if not initialized.

mount_kind: Option<String>

Describes what the textarea is mounted into.

Expected values: "overlay", "mount", "body", or None if not initialized.

device_pixel_ratio: Option<f64>

Device pixel ratio at the time the bridge was initialized or last updated.

textarea_value_chars: Option<usize>

Debug-only textarea metrics (DOM-reported).

These help diagnose candidate UI jitter and unexpected wrapping/scrolling behaviors across browsers and IMEs. Units are CSS pixels unless otherwise noted.

textarea_selection_start_utf16: Option<u32>

textarea_selection_end_utf16: Option<u32>

textarea_client_width_px: Option<i32>

textarea_client_height_px: Option<i32>

textarea_scroll_width_px: Option<i32>

textarea_scroll_height_px: Option<i32>

last_input_type: Option<String>

last_beforeinput_data: Option<String>

last_input_data: Option<String>

last_key_code: Option<KeyCode>

last_cursor_area: Option<Rect>

last_cursor_anchor_px: Option<(f32, f32)>

Where the hidden textarea is anchored (CSS px, relative to its positioning context).

This is derived from last_cursor_area by the web runner and helps diagnose candidate UI offsets (e.g. top-left vs center anchoring).

last_preedit_text: Option<String>

Truncated preedit text observed during compositionupdate.

last_preedit_cursor_utf16: Option<(u32, u32)>

Preedit cursor range in UTF-16 code units (begin, end) as reported by the textarea.

last_commit_text: Option<String>

Truncated committed text observed during compositionend or input.

recent_events: Vec<String>

Recent IME-related DOM events (debug-only ring buffer).

Intended to help diagnose ordering differences across browsers/IMEs.

beforeinput_seen: u64

input_seen: u64

suppressed_input_seen: u64

composition_start_seen: u64

composition_update_seen: u64

composition_end_seen: u64

cursor_area_set_seen: u64

Trait Implementations

impl Clone for WebImeBridgeDebugSnapshot

fn clone(&self) -> WebImeBridgeDebugSnapshot

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WebImeBridgeDebugSnapshot

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

Formats the value using the given formatter.

impl Default for WebImeBridgeDebugSnapshot

fn default() -> WebImeBridgeDebugSnapshot

Returns the “default value” for a type.

impl PartialEq for WebImeBridgeDebugSnapshot

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