Enum rustc_middle::ty::Visibility

pub enum Visibility {
    Public,
    Restricted(DefId),
    Invisible,
}

Variants

Public

Visible everywhere (including in other crates).

Restricted

Visible only in the given crate-local module.

Tuple Fields of Restricted

0: DefId

Invisible

Not visible anywhere in the local crate. This is the visibility of private external items.

Implementations

impl Visibility

pub fn from_hir(visibility: &Visibility<'_>, id: HirId, tcx: TyCtxt<'_>) -> Self

pub fn is_accessible_from<T: DefIdTree>(self, module: DefId, tree: T) -> bool

Returns true if an item with this visibility is accessible from the given block.

pub fn is_at_least<T: DefIdTree>(self, vis: Visibility, tree: T) -> bool

Returns true if this visibility is at least as accessible as the given visibility

pub fn is_visible_locally(self) -> bool

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
