Functions

from_attrs(attrs)

@spec from_attrs(map()) :: {:ok, t()} | {:error, {:missing_fields, [atom()]}}

Builds a BookEvent from a decoded (atom-keyed) websocket message.

Constructs the struct directly — no Ecto.Changeset — for the websocket hot path. Numeric fields (delivered as JSON strings) are coerced via Polymarket.Schemas.Coerce. Returns {:error, {:missing_fields, fields}} when a required field is absent.
