Image.Plug.VariantStore.ETS (image_plug v0.1.0)

In-memory ETS-backed implementation of Image.Plug.VariantStore.

A singleton owner process holds a :protected ETS table. Reads go straight to ETS; writes go through the owner process to serialise inserts and to populate the :inserted_at / :updated_at timestamps.

Configuration

Started by the :image_plug application with a default table name of :image_plug_variants. Variants are seeded from the application environment:

# config/config.exs
config :image_plug,
  variants: [
    {"thumbnail", "width=200,height=200,fit=cover,format=webp"},
    {"hero",      "width=1600,format=auto,quality=82"}
  ]

Each entry value can be:

• a Cloudflare-style options string (parsed by Image.Plug.Provider.Cloudflare.Options),

• a {provider, options_string, variant_options} triple,

• a pre-built Image.Plug.Pipeline, or

• a complete Image.Plug.Variant struct.

The implicit "public" variant is always seeded and represents Cloudflare's default "no transforms" behaviour. It can be overridden by adding an explicit "public" entry to the seeds.

Per-call options

Every callback accepts a :table keyword to address a non-default table — useful for tests and for hosts that run multiple isolated stores.
