pub fn tooling_decode_options() -> Result<DecodeOptions, String>Expand description
Decode options for a descriptor set produced by the caller’s own build,
honouring ELEMENT_MEMORY_LIMIT_ENV.
The override is an environment variable rather than a protoc plugin
option because the options string travels inside the request: it cannot
be read until the request has already been decoded.
§Errors
Returns a message naming the variable if its value is not a byte count or
unlimited / max.
