Struct gdnative_bindings_lily::Directory

pub struct Directory { /* fields omitted */ }

core class Directory inherits Reference (reference counted).

Official documentation

See the documentation of this class in the Godot engine’s official documentation. The method descriptions are generated from it and typically contain code samples in GDScript, not Rust.

Memory management

The lifetime of this object is automatically managed through reference counting.

Class hierarchy

Directory inherits methods from:

• Reference
• Object

Safety

All types in the Godot API have “interior mutability” in Rust parlance. To enforce that the official thread-safety guidelines are followed, the typestate pattern is used in the Ref and TRef smart pointers, and the Instance API. The typestate Access in these types tracks whether the access is unique, shared, or exclusive to the current thread. For more information, see the type-level documentation on Ref.

Implementations

impl Directory

pub fn new() -> Ref<Self, Unique>

Creates a new instance of this object.

This is a reference-counted type. The returned object is automatically managed by Ref.

pub fn change_dir(&self, todir: impl Into<GodotString>) -> GodotResult

Changes the currently opened directory to the one passed as an argument. The argument can be relative to the current directory (e.g. newdir or ../newdir), or an absolute path (e.g. /tmp/newdir or res://somedir/newdir). Returns one of the [enum Error] code constants (OK on success).

pub fn copy(
    &self,
    from: impl Into<GodotString>,
    to: impl Into<GodotString>
) -> GodotResult

Copies the from file to the to destination. Both arguments should be paths to files, either relative or absolute. If the destination file exists and is not access-protected, it will be overwritten. Returns one of the [enum Error] code constants (OK on success).

pub fn current_is_dir(&self) -> bool

Returns whether the current item processed with the last [method get_next] call is a directory (. and .. are considered directories).

pub fn dir_exists(&self, path: impl Into<GodotString>) -> bool

Returns whether the target directory exists. The argument can be relative to the current directory, or an absolute path.

pub fn file_exists(&self, path: impl Into<GodotString>) -> bool

Returns whether the target file exists. The argument can be relative to the current directory, or an absolute path.

pub fn get_current_dir(&self) -> GodotString

Returns the absolute path to the currently opened directory (e.g. res://folder or C:\tmp\folder).

pub fn get_current_drive(&self) -> i64

Returns the currently opened directory’s drive index. See [method get_drive] to convert returned index to the name of the drive.

pub fn get_drive(&self, idx: i64) -> GodotString

On Windows, returns the name of the drive (partition) passed as an argument (e.g. C:). On other platforms, or if the requested drive does not existed, the method returns an empty String.

pub fn get_drive_count(&self) -> i64

On Windows, returns the number of drives (partitions) mounted on the current filesystem. On other platforms, the method returns 0.

pub fn get_next(&self) -> GodotString

Returns the next element (file or directory) in the current directory (including . and .., unless skip_navigational was given to [method list_dir_begin]). The name of the file or directory is returned (and not its full path). Once the stream has been fully processed, the method returns an empty String and closes the stream automatically (i.e. [method list_dir_end] would not be mandatory in such a case).

pub fn get_space_left(&self) -> i64

On UNIX desktop systems, returns the available space on the current directory’s disk. On other platforms, this information is not available and the method returns 0 or -1.

pub fn list_dir_begin(
    &self,
    skip_navigational: bool,
    skip_hidden: bool
) -> GodotResult

Initializes the stream used to list all files and directories using the [method get_next] function, closing the current opened stream if needed. Once the stream has been processed, it should typically be closed with [method list_dir_end]. If skip_navigational is true, . and .. are filtered out. If skip_hidden is true, hidden files are filtered out.

Default Arguments

• skip_navigational - false
• skip_hidden - false

pub fn list_dir_end(&self)

Closes the current stream opened with [method list_dir_begin] (whether it has been fully processed with [method get_next] or not does not matter).

pub fn make_dir(&self, path: impl Into<GodotString>) -> GodotResult

Creates a directory. The argument can be relative to the current directory, or an absolute path. The target directory should be placed in an already existing directory (to create the full path recursively, see [method make_dir_recursive]). Returns one of the [enum Error] code constants (OK on success).

pub fn make_dir_recursive(&self, path: impl Into<GodotString>) -> GodotResult

Creates a target directory and all necessary intermediate directories in its path, by calling [method make_dir] recursively. The argument can be relative to the current directory, or an absolute path. Returns one of the [enum Error] code constants (OK on success).

pub fn open(&self, path: impl Into<GodotString>) -> GodotResult

Opens an existing directory of the filesystem. The path argument can be within the project tree (res://folder), the user directory (user://folder) or an absolute path of the user filesystem (e.g. /tmp/folder or C:\tmp\folder). Returns one of the [enum Error] code constants (OK on success).

pub fn remove(&self, path: impl Into<GodotString>) -> GodotResult

Deletes the target file or an empty directory. The argument can be relative to the current directory, or an absolute path. If the target directory is not empty, the operation will fail. Returns one of the [enum Error] code constants (OK on success).

pub fn rename(
    &self,
    from: impl Into<GodotString>,
    to: impl Into<GodotString>
) -> GodotResult

Renames (move) the from file to the to destination. Both arguments should be paths to files, either relative or absolute. If the destination file exists and is not access-protected, it will be overwritten. Returns one of the [enum Error] code constants (OK on success).

Methods from Deref<Target = Reference>

pub fn init_ref(&self) -> bool

Initializes the internal reference counter. Use this only if you really know what you are doing. Returns whether the initialization was successful.

Trait Implementations

impl Debug for Directory

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

Formats the value using the given formatter.

impl Deref for Directory

type Target = Reference

The resulting type after dereferencing.

fn deref(&self) -> &Reference

Dereferences the value.

impl DerefMut for Directory

fn deref_mut(&mut self) -> &mut Reference

Mutably dereferences the value.

impl GodotObject for Directory

type RefKind = RefCounted

The memory management kind of this type. This modifies the behavior of the Ref smart pointer. See its type-level documentation for more information.

fn class_name() -> &'static str

fn null() -> Null<Self>

Creates an explicitly null reference of Self as a method argument. This makes type inference easier for the compiler compared to Option.

fn new() -> Ref<Self, Unique> where
    Self: Instanciable, 

Creates a new instance of Self using a zero-argument constructor, as a Unique reference.

fn cast<T>(&self) -> Option<&T> where
    T: GodotObject + SubClass<Self>, 

Performs a dynamic reference downcast to target type.

fn upcast<T>(&self) -> &T where
    Self: SubClass<T>,
    T: GodotObject, 

Performs a static reference upcast to a supertype that is guaranteed to be valid.

unsafe fn assume_shared(&self) -> Ref<Self, Shared>

Creates a persistent reference to the same Godot object with shared thread access.

unsafe fn assume_thread_local(&self) -> Ref<Self, ThreadLocal> where
    Self: GodotObject<RefKind = RefCounted>, 

Creates a persistent reference to the same Godot object with thread-local thread access.

unsafe fn assume_unique(&self) -> Ref<Self, Unique>

Creates a persistent reference to the same Godot object with unique access.

unsafe fn try_from_instance_id<'a>(id: i64) -> Option<TRef<'a, Self, Shared>>

Recovers a instance ID previously returned by Object::get_instance_id if the object is still alive. See also TRef::try_from_instance_id.

unsafe fn from_instance_id<'a>(id: i64) -> TRef<'a, Self, Shared>

Recovers a instance ID previously returned by Object::get_instance_id if the object is still alive, and panics otherwise. This does NOT guarantee that the resulting reference is safe to use.
