#[derive(MacroInput)]
{
    // Attributes available to this derive:

automatically derive From<&[syn::Attribute]>, fn lint() -> &'static impl Lint<Vec<syn::Attribute>> and fn strip(attrs: &mut Vec<syn::Attribute>)

Example

#[derive(MacroInput)]
pub struct Input {
    pub flag: Option<()>,
    pub optional: Option<i32>,
    #[macro_input(default_value = 3)]
    pub with_default: i32,
    pub required: i32,
}

#[derive(MacroInput)]
#[macro_input(rename = "YetAnotherName")]
pub struct OtherInput {
    #[macro_input(rename = "new_name")]
