impl FileSystem for MemoryFS
source§fn read_dir(
&self,
path: &str
) -> VfsResult<Box<dyn Iterator<Item = String> + Send>>
fn read_dir( &self, path: &str ) -> VfsResult<Box<dyn Iterator<Item = String> + Send>>
Iterates over all direct children of this directory path
NOTE: the returned String items denote the local bare filenames, i.e. they should not contain “/” anywhere
source§fn create_dir(&self, path: &str) -> VfsResult<()>
fn create_dir(&self, path: &str) -> VfsResult<()>
Creates the directory at this path Read more
source§fn open_file(&self, path: &str) -> VfsResult<Box<dyn SeekAndRead + Send>>
fn open_file(&self, path: &str) -> VfsResult<Box<dyn SeekAndRead + Send>>
Opens the file at this path for reading
source§fn create_file(&self, path: &str) -> VfsResult<Box<dyn SeekAndWrite + Send>>
fn create_file(&self, path: &str) -> VfsResult<Box<dyn SeekAndWrite + Send>>
Creates a file at this path for writing
source§fn append_file(&self, path: &str) -> VfsResult<Box<dyn SeekAndWrite + Send>>
fn append_file(&self, path: &str) -> VfsResult<Box<dyn SeekAndWrite + Send>>
Opens the file at this path for appending
source§fn metadata(&self, path: &str) -> VfsResult<VfsMetadata>
fn metadata(&self, path: &str) -> VfsResult<VfsMetadata>
Returns the file metadata for the file at this path
source§fn set_creation_time(&self, path: &str, time: SystemTime) -> VfsResult<()>
fn set_creation_time(&self, path: &str, time: SystemTime) -> VfsResult<()>
Sets the files creation timestamp, if the implementation supports it
source§fn set_modification_time(&self, path: &str, time: SystemTime) -> VfsResult<()>
fn set_modification_time(&self, path: &str, time: SystemTime) -> VfsResult<()>
Sets the files modification timestamp, if the implementation supports it
source§fn set_access_time(&self, path: &str, time: SystemTime) -> VfsResult<()>
fn set_access_time(&self, path: &str, time: SystemTime) -> VfsResult<()>
Sets the files access timestamp, if the implementation supports it
source§fn exists(&self, path: &str) -> VfsResult<bool>
fn exists(&self, path: &str) -> VfsResult<bool>
Returns true if a file or directory at path exists, false otherwise
source§fn copy_file(&self, _src: &str, _dest: &str) -> VfsResult<()>
fn copy_file(&self, _src: &str, _dest: &str) -> VfsResult<()>
Copies the src path to the destination path within the same filesystem (optional)
