minus-squareEphera@lemmy.mllinkfedilinkarrow-up21·edit-29 months agoYou must’ve read that wrong. The first example, but formatted differently: let value = "My name is Rho."; let result = unformat!("My {} is {}.", value); Now, result contains: Some(("name", "Rho")) …because the words “name” and “Rho” in value happened to be at the position of the {}-slots in the unformat!()-pattern.

Now,
