Trait CustomStyleProperty 

pub trait CustomStyleProperty:
    'static
    + Send
    + Sync {
    // Required methods
    fn as_any(&self) -> &(dyn Any + 'static);
    fn eq_property(&self, other: &(dyn CustomStyleProperty + 'static)) -> bool;
}

A style property defined outside of GPUI’s core style structs.

Engines and forks carry their own rendering extensions - a backdrop blur radius, a custom shader’s parameters - through the style cascade by defining a type and setting it with Styled::custom_style, rather than adding a field to Style that every consumer of this crate has to know about.

The type itself keys the property, so a reader recovers exactly the type that was set. Any Send + Sync + PartialEq + 'static type is a custom property as-is; there is nothing to implement. Properties must be PartialEq because merging and subtracting style refinements diffs them.

Required Methods

fn as_any(&self) -> &(dyn Any + 'static)

Upcasts to Any so CustomStyles::get can recover the concrete type.

fn eq_property(&self, other: &(dyn CustomStyleProperty + 'static)) -> bool

Compares two properties that share a concrete type.

Dyn Compatibility

This trait is dyn compatible.

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