defmodule Weave.Image do
@moduledoc """
Thumbnail processing powered by Rust.
Downloads images, resizes to 256x256 WebP thumbnails, and computes
deterministic storage keys based on source URL SHA-256.
"""
@doc """
Computes the thumbnail storage key from a source URL.
Returns `"thumbnails/{sha256_hex[0..32]}.webp"`.
## Examples
iex> Weave.Image.thumbnail_key("https://example.com/photo.jpg")
"thumbnails/" <> _rest = Weave.Image.thumbnail_key("https://example.com/photo.jpg")

@doc """
Downloads an image, resizes to 256x256 WebP, and computes the storage key.
Returns `{:ok, {key, webp_bytes}}` or `{:error, reason}`.
