Trait FromVarargs 

pub trait FromVarargs: Sized {
    // Required method
    fn read<'a>(args: &mut Varargs<'a>) -> Result<Self, Vec<ArgumentError<'a>>>;
}

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>>,
}

Required Methods

fn read<'a>(args: &mut Varargs<'a>) -> Result<Self, Vec<ArgumentError<'a>>>

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.
