Expand description

Data type used to encode properties in the payload.

There are two possible types: scalars and lists. Lists are a sequence of scalars with a leading integer value defining how many elements the list contains.

Variants

Scalar(ScalarType)

Simple, “one-number” type.

List(ScalarType, ScalarType)

Defines a sequence of scalars with the same type.

First value is the index type which should be an integer variant, Encoded in ascii, you always get the same number in the file (for example 32 or 17). Hence, a good choice is mainly important for internal representation and binary encoding. T he possible trade-off should be obvious: List length/flexibility against storage size. Though this obviously depends on your specific use case.

Second value is the type of the list elemetns.

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

Should always be Self

The inverse inclusion map: attempts to construct self from the equivalent element of its superset. Read more

Checks if self is actually part of its subset T (and can be converted to it).

Use with care! Same as self.to_subset but without any property checks. Always succeeds.
