Expand description
Trait for structures that can be parsed from Varargs
.
This trait can be derived for structure types where each type implements FromVariant
.
The order of fields matter for this purpose:
ⓘ
#[derive(FromVarargs)]
struct MyArgs {
foo: i32,
bar: String,
#[opt] baz: Option<Ref<Node>>,
}

Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
