pub struct PrimitiveLoader<T>(_);
Expand description

Primitive type value loader.

This does minimal checks about data_type and label. If you want to check property type precisely, you should make another loader type by purpose.

This loader automatically does safe conversion, i.e. you can load i32 value from raw i16 attribute.

Note that f32 and f64 will be implicitly converted in both directions by this loader.
