Filetype-specific content of a file

Variants

Regular

Regular file

Fields

content: Vec<u8>

File content

is_native_executable: bool

Whether this file is a native binary that can be exec’ed

Directory

Directory

Fields

files: HashMap<Rc<UnixStr>, Rc<RefCell<Inode>>>

Files contained in this directory

The keys of the hashmap are filenames without any parent directory components. The hashmap does not contain “.” or “..”.

Fifo

Named pipe

Fields

content: VecDeque<u8>

Content of the pipe

readers: usize

Number of open file descriptions reading from this pipe

writers: usize

Number of open file descriptions writing to this pipe

Symlink

Symbolic link

Fields

target: PathBuf

Path to the file referenced by this symlink

Implementations

impl FileBody

pub fn new<T: Into<Vec<u8>>>(bytes: T) -> Self

Creates a regular file body with the given content.

pub const fn type(&self) -> FileType

Returns the type of the file.

pub fn size(&self) -> usize

Returns the size of the file.

Trait Implementations

impl Clone for FileBody

fn clone(&self) -> FileBody

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FileBody

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

Formats the value using the given formatter.

impl Default for FileBody

The default file body is an empty regular file.

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for FileBody

fn eq(&self, other: &FileBody) -> 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 TryFrom<&FileBody> for VirtualDir<IntoIter<Rc<UnixStr>>>

Creates a VirtualDir that yields entries of a directory.

This function will fail if the given file body is not a directory.

type Error = Errno

The type returned in the event of a conversion error.

fn try_from(file: &FileBody) -> Result<Self, Errno>

Performs the conversion.

impl Eq for FileBody

impl StructuralPartialEq for FileBody
