minus-squarenebeker@programming.devlinkfedilinkEnglisharrow-up0·2 months agoAnd bow to the compiler’s whims? I think not! This shouldn’t compile, because .into needs the type from the left side and let needs the type from the right side.
minus-squareHaradion@lemmy.mllinkfedilinkarrow-up2·1 month agoIf type constraints later in the function let the compiler infer the type, this syntax totally works.
