Version 0.5 Property Constructor API [Types]

[hummingly]

Property builder types use defined value types as defined.

Closes #11 and #10 .

Splitting the PR would allow to push a new version with numeric value support.

This requires a few things.

• Property needs actual value type.
• Text type.
• Check constructors of numeric properties. Internally it can be a i32 but should be another type due to semantics.

enum IcsValue {
    Integer(i32),
    Float(f32),
    Text(Cow<'a, str>),
     // Non-exhaustive pattern
}

After playing around with the above strategy it would be better to keep Property as is and instead create a writer. This means the builder types would implement a trait instead and this would be written immediately.

struct IcsWriter {..}

impl IcsWriter {
    fn write(property: PropertyWrite) {
        write!(...)
    }
}

trait PropertyWrite {
    fn name() -> impl Display;
    fn value() -> impl Display;
    fn parameters() -> impl Iterator<K, V>
}

However, version 0.5 should add first the type constructors.

I will keep this branch as reference for the writer-api.
