Defined in:: lib/sequel_opal_runtime_patches.rb

Overview

String-buffer overrides: Sequel’s Dataset#sql_string_origin and literal_append allocate plain String instances which Opal treats as immutable — the ‘<<` accumulator pattern raises NotImplementedError. Replace the allocation sites with HomuraSqlBuffer, which implements the Sequel-expected subset of String (from lib/sequel_opal_patches.rb).
