Crate ftui_web 

ftui-web provides a WASM-friendly backend implementation for FrankenTUI.

Design goals:

• Host-driven I/O: the embedding environment (JS) pushes input events and size changes.
• Deterministic time: the host advances a monotonic clock explicitly.
• No blocking / no threads: suitable for wasm32-unknown-unknown.

This crate intentionally does not bind to wasm-bindgen yet. The primary purpose is to provide backend building blocks that frankenterm-web can wrap with a stable JS API.

Modules

pane_pointer_capture

Deterministic web pointer-capture adapter for pane drag/resize interactions.

session_record

Deterministic session recording and replay for WASM (bd-lff4p.3.7).

step_program

Step-based WASM program runner for FrankenTUI.

Structs

DeterministicClock

Deterministic monotonic clock controlled by the host.

WebBackend

A minimal, host-driven WASM backend.

WebEventSource

Host-driven event source for WASM.

WebFlatPatchBatch

Compact, flat patch payload for JS/WASM transport.

WebOutputs

Captured presentation outputs for host consumption.

WebPatchCell

One GPU patch cell payload (bg, fg, glyph, attrs) matching the frankenterm-web applyPatch schema.

WebPatchRun

One contiguous run of changed cells starting at linear offset.

WebPatchStats

Aggregate patch-upload stats for host instrumentation and JSONL reporting.

WebPresenter

WASM presenter that captures buffers and logs for the host.

Enums

WebBackendError

Web backend error type.
