Static kCTBaselineReferenceInfoAttributeName 

pub unsafe static kCTBaselineReferenceInfoAttributeName: &'static CFString

Available on crate feature CTStringAttributes only.

Key to reference a baseline info dictionary for the reference baseline.

Value must be a CFDictionaryRef. All glyphs in a run are assigned a baseline class and then aligned to the offset for that class in the reference baseline baseline info. See the discussion of kCTBaselineInfoAttributeName for information about the contents of the dictionary. You can also use the kCTBaselineReferenceFont key to specify that the baseline offsets of a particular CTFontRef should be used as the reference offsets.
