Struct marker_api::ast::Visibility

#[repr(C)]
pub struct Visibility<'ast> { /* private fields */ }

The declared visibility of an item or field.

Note that this is only the syntactic visibility. The item or field might be reexported with a higher visibility, or have a high default visibility.

// An item without a visibility
fn moon() {}

// A public item
pub fn sun() {}

// An item with a restricted scope
pub(crate) fn star() {}

pub trait Planet {
    // An item without a visibility. But it still has the semantic visibility
    // of `pub` as this is inside a trait declaration.
    fn mass();
}
