class IdType

template <typename IdTraits>

class IdType

Defined at line 56 of file ../../src/graphics/display/lib/api-types/cpp/id-type.h

Newtype pattern implementation for integer identifiers.

Instances are value types, and support being stored in containers. Copying is

supported. The destructor is trivial.

Instances support incrementing for sequential ID generation.

Instances support being used as container keys, by implementing comparison

with strict ordering guarantees and a std::hash specialization.

Instances support being used with std::format(), by delegating to the

std::formatter specialization for the underlying value type.

This type is a zero-cost abstraction. Compiler optimizations will remove any

overhead associated with it.

`IdTraits` must be a traits structure with the same type aliases and static

methods as `DefaultIdTraits`.
