Struct Module 

pub(crate) struct Module<'hir> {
    pub(crate) name: Symbol,
    pub(crate) where_inner: Span,
    pub(crate) mods: Vec<Module<'hir>>,
    pub(crate) def_id: LocalDefId,
    pub(crate) renamed: Option<Symbol>,
    pub(crate) import_id: Option<LocalDefId>,
    pub(crate) items: FxIndexMap<(LocalDefId, Option<Symbol>), (&'hir Item<'hir>, Option<Symbol>, Vec<LocalDefId>)>,
    pub(crate) inlined_foreigns: FxIndexMap<(DefId, Option<Symbol>), (Res, LocalDefId)>,
    pub(crate) foreigns: Vec<(&'hir ForeignItem<'hir>, Option<Symbol>, Option<LocalDefId>)>,
}

This module is used to store stuff from Rust’s AST in a more convenient manner (and with prettier names) before cleaning.

Fields

name: Symbol

where_inner: Span

mods: Vec<Module<'hir>>

def_id: LocalDefId

renamed: Option<Symbol>

import_id: Option<LocalDefId>

items: FxIndexMap<(LocalDefId, Option<Symbol>), (&'hir Item<'hir>, Option<Symbol>, Vec<LocalDefId>)>

The key is the item ItemId and the value is: (item, renamed, Vec<import_id>). We use FxIndexMap to keep the insert order.

import_id needs to be a Vec because we live in a dark world where you can have code like:

mod raw {
    pub fn foo() {}
}

/// Foobar
pub use raw::foo;

pub use raw::*;

So in this case, we don’t want to have two items but just one with attributes from all non-glob imports to be merged. Glob imports attributes are always ignored, whether they’re shadowed or not.

inlined_foreigns: FxIndexMap<(DefId, Option<Symbol>), (Res, LocalDefId)>

(def_id, renamed) -> (res, local_import_id)

inlined_foreigns only contains extern items that are cross-crate inlined.

Locally inlined extern items are stored in foreigns with the import_id set, analogous to how items is.

foreigns: Vec<(&'hir ForeignItem<'hir>, Option<Symbol>, Option<LocalDefId>)>

(item, renamed, import_id)

Implementations

impl Module<'_>

pub(crate) fn new( name: Symbol, def_id: LocalDefId, where_inner: Span, renamed: Option<Symbol>, import_id: Option<LocalDefId>, ) -> Self

pub(crate) fn where_outer(&self, tcx: TyCtxt<'_>) -> Span

Trait Implementations

impl<'hir> Debug for Module<'hir>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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.
