pub trait StructAttributeHasLengthField<const HAS_LENGTH_FIELD: bool>: StructMeta { }Expand description
A trait implemented for all structs with a boolean determining whether they have a length field.
NOTE: A generic parameter is used here which allows for optional further trait implementations.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
