While parsing enum variant, the error message always disappear Because the error message that emit out is from main error of parser The information of enum variant disappears while parsing enum variant with error We only check the syntax of expecting token, i.e, in case #103869 It will error it without telling the message that this error is from pasring enum variant. Propagate the sub-error from parsing enum variant to the main error of parser by chaining it with map_err Check the sub-error before emitting the main error of parser and attach it.
