NanoPBOptions

This is the inner options message, which basically defines options for
a field. When it is used in message or file scope, it applies to all
fields.

decode oneof as anonymous union

Data type for storage associated with callback fields.

Data type for storage associated with callback fields.

Callback function used for encoding and decoding.
Prior to nanopb-0.4.0, the callback was specified in per-field pb_callback_t
structure. This is still supported, but does not work inside e.g. oneof or pointer
fields. Instead, a new method allows specifying a per-message callback that
will be called for all callback fields in a message type.

Set default value for has_ fields.

Select the size of field descriptors. This option has to be defined
for the whole message, not per-field. Usually automatic selection is
ok, but if it results in compilation errors you can increase the field
size here.

Generate an enum->string mapping function (can take up lots of space).

Automatic includes to exclude from generated `.pb.h`
Same as nanopb_generator.py command line flag -x.

Set the FT_DEFAULT field conversion strategy.
A field that can become a static member of a c struct (e.g. int, bool, etc)
will be a a static field.
Fields with dynamic length are converted to either a pointer or a callback.

Generate repeated field with fixed count

Generate bytes arrays with fixed length

Size of integer fields. Can save some memory if you don't need
full 32 bits for the value.

Use long names for enums, i.e. EnumName_EnumValue.

Shorten or remove package names from type names.
This option applies only on the file level.

Allocated number of entries in arrays ('repeated' fields)

Maximum length for 'string' fields. Setting this is equivalent
to setting max_size to a value of length+1.

Allocated size for 'bytes' and 'string' fields.
For string fields, this should include the space for null terminator.

integer type tag for a message

Generate oneof fields as normal optional fields instead of union.

Package name that applies only for nanopb.

Package name that applies only for nanopb.

Add 'packed' attribute to generated enums.

Add 'packed' attribute to generated structs.
Note: this cannot be used on CPUs that break on unaligned
accesses to variables.

Proto3 singular field does not generate a "has_" flag

Force proto3 messages to have no "has_" flag.
This was default behavior until nanopb-0.4.0.

Skip this message

Due to historical reasons, nanopb orders fields in structs by their tag number
instead of the order in .proto. Set this to false to keep the .proto order.
The default value will probably change to false in nanopb-0.5.0.

Generate message-level callback that is called before decoding submessages.
This can be used to set callback fields for submsgs inside oneofs.

Force type of field (callback or static allocation)

Override type of the field in generated C code. Only to be used with related field types
