Detailed Description

Represents a semantic annotation as a pair of class label and confidence score.

Semantic combines a discrete category identifier (Label) with a continuous confidence measure (Confidence), making it suitable for probabilistic semantic segmentation of point clouds and map nodes. It is a lightweight, trivially-copyable aggregate, fully ordered via <=>, and supports std::ostream streaming (as "label: confidence") and std::format.

Intended for use as a per-point or per-node attribute in semantic mapping, where both the class and its associated certainty are required.

◆ operator<=>

constexpr auto operator<=>	(	Semantic	lhs,
		Semantic	rhs
	)

friend

Three-way comparison (lexicographic on label then value).

Parameters

[in]	lhs	Left operand.
[in]	rhs	Right operand.

Returns: Comparison result.

◆ operator==

constexpr bool operator==	(	Semantic	lhs,
		Semantic	rhs
	)

friend

Equality comparison.

Parameters

[in]	lhs	Left operand.
[in]	rhs	Right operand.

Returns: True if both label and confidence are equal.
