Struct Alias 

pub struct Alias {
    pub uses: usize,
    /* private fields */
}

Represents an item that acts like it is locally-defined, but is actually externally-defined.

These “aliases” do not have a concrete representation in the module, but are instead resolved during compilation to refer directly to the aliased item.

Fields

uses: usize

The number of times this import has been used locally.

Implementations

impl Alias

pub fn new(visibility: Visibility, name: Ident, target: AliasTarget) -> Self

Creates a new item alias called name, which resolves to target.

pub fn with_docs(self, docs: Option<Span<String>>) -> Self

Adds documentation to this alias.

pub fn docs(&self) -> Option<Span<&str>>

Returns the documentation associated with this item.

pub const fn visibility(&self) -> Visibility

Returns the visibility of this alias

pub fn name(&self) -> &Ident

Returns the name of this alias within its containing module.

If the item is simply re-exported with the same name, this will be equivalent to self.target().name

pub fn target(&self) -> &AliasTarget

Returns the target of this alias

pub fn target_mut(&mut self) -> &mut AliasTarget

Returns a mutable reference to the target of this alias

pub fn is_absolute(&self) -> bool

Returns true if this alias uses an absolute target path

pub fn is_renamed(&self) -> bool

Returns true if this alias uses a different name than the target

pub fn is_used(&self) -> bool

Returns true if this import has at least one use in its containing module.

Trait Implementations

impl Clone for Alias

fn clone(&self) -> Alias

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Alias

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

Formats the value using the given formatter.

impl From<Alias> for Form

fn from(alias: Alias) -> Self

Converts to this type from the input type.

impl PartialEq for Alias

fn eq(&self, other: &Alias) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PrettyPrint for Alias

fn render(&self) -> Document

The core of the PrettyPrint functionality.

fn to_pretty_string(&self) -> String

Produce a String containing the results of pretty-printing this object.

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

Pretty-print this object to the given core::fmt::Formatter.

impl Spanned for Alias

fn span(&self) -> SourceSpan

impl Eq for Alias
