Decodes an unknown input against a schema, returning an Option that is Some with the decoded value on success or None for schema mismatches.

When to use

Use when you do not know the input type statically and only need to know whether decoding succeeded.

Details

Prefer this over decodeUnknownExit or decodeUnknownEffect when you don't need error details. For input already typed as the schema's Encoded type use decodeOption. Options may be provided either when creating the decoder or when applying it; application options override creation options.

Gotchas

Only causes made entirely of schema issues are converted to None. Causes that contain defects, interruptions, or other non-schema reasons throw instead.
