Implementations
pub fn create<'bldr: 'args, 'args: 'mut_bldr, 'mut_bldr>(
_fbb: &'mut_bldr mut FlatBufferBuilder<'bldr>,

) -> WIPOffset<Field<'bldr>>
Whether or not this field can contain nulls. Should be true in general.
This is the type of the decoded value if the field is dictionary encoded.
Present only if the field is dictionary encoded.
