Struct ExternPreludeEntry

pub(crate) struct ExternPreludeEntry<'ra> {
    pub(crate) item_binding: Option<Interned<'ra, NameBindingData<'ra>>>,
    pub(crate) flag_binding: Cell<Option<Interned<'ra, NameBindingData<'ra>>>>,
    pub(crate) only_item: bool,
    pub(crate) introduced_by_item: bool,
}

Fields

item_binding: Option<Interned<'ra, NameBindingData<'ra>>>

Binding from an extern crate item.

flag_binding: Cell<Option<Interned<'ra, NameBindingData<'ra>>>>

Binding from an --extern flag, lazily populated on first use.

only_item: bool

There was no --extern flag introducing this name, flag_binding doesn’t need to be populated.

introduced_by_item: bool

item_binding is non-redundant, happens either when only_item is true, or when extern crate introducing item_binding used renaming.

Trait Implementations

impl<'ra> Clone for ExternPreludeEntry<'ra>

fn clone(&self) -> ExternPreludeEntry<'ra>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'ra> Default for ExternPreludeEntry<'ra>

fn default() -> ExternPreludeEntry<'ra>

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
