Enum PropertyType

pub enum PropertyType {
    Scalar(ScalarType),
    List(ScalarType, ScalarType),
}

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.

Trait Implementations

impl Clone for PropertyType

fn clone(&self) -> PropertyType

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PropertyType

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for PropertyType

fn eq(&self, other: &PropertyType) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
