Name	Remarks
FStaticEvalArgs	Encapsulates the StaticEval arguments.

Name	Type	Remarks	Include Path
CompressedKeys	TArray< uint8 >	Compressed keys, used only outside of the editor	Curves/RichCurve.h
CompressionFormat	TEnumAsByte< ERichCurveCompressionFormat >	Compression format used by CompressedKeys	Curves/RichCurve.h
ConstantValueNumKeys	TConstantValueNumKeys	If the compression format is constant, this is the value returned Inline here to reduce the likelihood of accessing the compressed keys data for the common case of constant/zero/empty curves When a curve is linear/cubic/mixed, the constant float value isn't used and instead we use the number of keys	Curves/RichCurve.h
KeyTimeCompressionFormat	TEnumAsByte< ERichCurveKeyTimeCompressionFormat >	Compression format used to pack the key time	Curves/RichCurve.h
PostInfinityExtrap	TEnumAsByte< ERichCurveExtrapolation >	Post-infinity extrapolation state	Curves/RichCurve.h
PreInfinityExtrap	TEnumAsByte< ERichCurveExtrapolation >	Pre-infinity extrapolation state	Curves/RichCurve.h
