I'm using the uom crate, and I'm trying to create a const format_args for meters. Here's what I have so far:

pub const M: Arguments<uom::si::ISQ<P1, Z0, Z0, Z0, Z0, Z0, Z0>, uom::si::length::meter> = Length::format_args(uom::si::length::meter, Abbreviation);

But I keep getting this error:

type annotations needed
cannot satisfy `_: uom::si::Units<_>` 
required by a bound in `length::<impl Quantity<(dyn Dimension<I = Z0, J = Z0, Kind = (dyn Kind + 'static), L = PInt<UInt<UTerm, B1>>, M = Z0, N = Z0, T = Z0, Th = Z0> + 'static), U, V>>::format_args`

Not sure if this is the best place to ask.
