I have the following so far:
let values: Vec<Result<f64, std::num::ParseFloatError>> =
parts.map(|value| value.parse::<f64>()).collect();
But what I really want is a Result<Vec<f64>, std::num::ParseFloatError>
- and for it to return early if it does fail to parse any of the values.

Ask, and you shall receive! Just change the type of values
(playground):
let values: Result<Vec<f64>, std::num::ParseFloatError> =
parts.map(|value| value.parse::<f64>()).collect();
This works because Result
implements FromIterator
.
