Struct UseTree

pub struct UseTree { /* private fields */ }

Implementations

impl UseTree

pub fn remove_recursive(self)

Deletes the usetree node represented by the input. Recursively removes parents, including use nodes that become empty.

pub fn get_or_create_use_tree_list(&self) -> UseTreeList

pub fn split_prefix(&self, prefix: &Path)

Splits off the given prefix, making it the path component of the use tree, appending the rest of the path to all UseTreeList items.

Examples

prefix$0::suffix -> prefix::{suffix}

prefix$0 -> prefix::{self}

prefix$0::* -> prefix::{*}

pub fn wrap_in_tree_list(&self) -> Option<()>

Wraps the use tree in use tree list with no top level path (if it isn’t already).

Examples

foo::bar -> {foo::bar}

{foo::bar} -> {foo::bar}

impl UseTree

pub fn path(&self) -> Option<Path>

pub fn rename(&self) -> Option<Rename>

pub fn use_tree_list(&self) -> Option<UseTreeList>

pub fn star_token(&self) -> Option<SyntaxToken>

pub fn coloncolon_token(&self) -> Option<SyntaxToken>

impl UseTree

pub fn is_simple_path(&self) -> bool

pub fn parent_use_tree_list(&self) -> Option<UseTreeList>

pub fn top_use_tree(&self) -> UseTree

Trait Implementations

impl AstNode for UseTree

fn can_cast(kind: SyntaxKind) -> bool

fn cast(syntax: SyntaxNode) -> Option<Self>

fn syntax(&self) -> &SyntaxNode

fn clone_for_update(&self) -> Self

where Self: Sized,

fn clone_subtree(&self) -> Self

where Self: Sized,

impl Clone for UseTree

fn clone(&self) -> UseTree

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UseTree

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

Formats the value using the given formatter.

impl Display for UseTree

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

Formats the value using the given formatter.

impl Hash for UseTree

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for UseTree

fn eq(&self, other: &UseTree) -> 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.
