Struct NoDefault

source 
pub struct NoDefault;
Expand description

A pseudo-field that cannot be written (returns an error at runtime)

This is useful for types that do not have a default representation (e.g. PT_DYN types)

Note: all event fields are generated as Option<T>, so there is always a possibility that we get to write a default value for a field that does not have one.
