WebAssembly is low level — you essentially get to define global variables, an array of memory, and some functions to operate on them. It’s not batteries-included.

SilverOrb provides these batteries so common tasks are easier. They are:

• StringBuilder for assembling strings from dynamic parts.
• IntFormatter for converting integers to strings.
• ISO8601 for parsing dates and times.
• Arena allocator for memory management.
• ASCII (coming soon) for operating on ASCII strings.
• UTF8 (coming soon) for operating on UTF-8 strings.
• IntParser (coming soon) for converting strings to integers.
• XMLBuilder (coming soon) for assembling XML from dynamic parts.
• FormData (coming soon) for decoding/encoding application/x-www-form-urlencoded strings.
• URLSearchParams (coming soon) for decoding/encoding URL query strings.
• URL (coming soon) for decoding/encoding URLs.
• Request (later) for encoding HTTP/1 requests.
• Response (later) for encoding HTTP/1 responses.
• Iterator (coming soon) for creating a custom sequence type that can be iterated through.

The package can be installed by adding silver_orb to your list of dependencies in mix.exs:

def deps do
  [
    {:silver_orb, "~> 0.0.10"}
  ]
end
