Struct cap_std::fs_utf8::DirEntry

pub struct DirEntry { /* private fields */ }

Available on crate feature fs_utf8 only.

Entries returned by the ReadDir iterator.

This corresponds to std::fs::DirEntry.

Unlike std::fs::DirEntry, this API has no DirEntry::path, because absolute paths don’t interoperate well with the capability model.

There is a file_name function, however there are also open, open_with, open_dir, remove_file, and remove_dir functions for opening or removing the entry directly, which can be more efficient and convenient.

There is no from_std method, as std::fs::DirEntry doesn’t provide a way to construct a DirEntry without opening directories by ambient paths.

Implementations

impl DirEntry

pub fn from_cap_std(cap_std: DirEntry) -> Self

Constructs a new instance of Self from the given cap_std::fs::DirEntry.

pub fn open(&self) -> Result<File>

Open the file for reading.

pub fn open_with(&self, options: &OpenOptions) -> Result<File>

Open the file with the given options.

pub fn open_dir(&self) -> Result<Dir>

Open the entry as a directory.

pub fn remove_file(&self) -> Result<()>

Removes the file from its filesystem.

pub fn remove_dir(&self) -> Result<()>

Removes the directory from its filesystem.

pub fn metadata(&self) -> Result<Metadata>

Returns the metadata for the file that this entry points at.

This corresponds to std::fs::DirEntry::metadata.

pub fn file_type(&self) -> Result<FileType>

Returns the file type for the file that this entry points at.

This corresponds to std::fs::DirEntry::file_type.

pub fn file_name(&self) -> Result<String>

Returns the bare file name of this directory entry without any other leading path component.

This function returns an Err in the case that the file name isn’t encodable as UTF-8.

If the arf_strings feature is enabled, unencodable names are translated to UTF-8 using arf-strings.

This corresponds to std::fs::DirEntry::file_name.

impl Debug for DirEntry

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

Formats the value using the given formatter.
