Trait Attribute 

pub trait Attribute: Sized {
    const DEFINDEX: u32;
    const ATTRIBUTE: AttributeDef;
    const USES_FLOAT_VALUE: bool;

    // Required method
    fn attribute_float_value(&self) -> Option<f32>;

    // Provided method
    fn attribute_value(&self) -> AttributeValue { ... }
}

Attribute values for an item attribute.

Required Associated Constants

const DEFINDEX: u32

The defindex.

const ATTRIBUTE: AttributeDef

The attribute definition.

const USES_FLOAT_VALUE: bool

Not part of the schema.

This is a marker to specify which attribute field is meaningful to us in obtaining the attribute’s value.

Kill Count Example

{
    "defindex": 214,
    "value": 918,
    "float_value": 1.28639199025018207e-42
}

This is the “kill_eater” attribute. “918” refers to the number of kills. The float_value field is the same number as a 32-bit float.

You can perform the conversions yourself with the following code:

let value = 918u32;
let float_value = 1.28639199025018207e-42f32;
 
assert_eq!(f32::from_bits(value), float_value);
assert_eq!(float_value.to_bits(), value);

Sheen Example

{
    "defindex": 2014,
    "value": 1086324736,
    "float_value": 6
}

This is the “killstreak_idleeffect” attribute. “6” refers to the associated sheen ( Sheen::VillainousViolet), but is stored in the float_value field, unlike “kill_eater”. The value field is the same number as a 32-bit float.

While both values refer to the same value, and internally the attribute’s value is its float_value, there are many cases where the float_value doesn’t mean anything to us unless converted to a 32-bit integer from its bits, and if the float_value does mean something to us we don’t want to convert it to an integer. This can be a little confusing, but it’s just how the API is.

By marking each attribute with a uses_float_value flag, we can indicate whether the float_value field is meaningful to use for that attribute.

Required Methods

fn attribute_float_value(&self) -> Option<f32>

Gets the attribute float value.

Provided Methods

fn attribute_value(&self) -> AttributeValue

Gets the attribute value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
