[−][src]Struct sgx_tstd::sgxfs::SgxFile
A reference to an open file on the filesystem.
An instance of a File
can be read and/or written depending on what options
it was opened with. Files also implement Seek
to alter the logical cursor
that the file contains internally.
Files are automatically closed when they go out of scope.
Methods
impl SgxFile
[src]
pub fn open<P: AsRef<Path>>(path: P) -> Result<SgxFile>
[src]
Attempts to open a file in read-only mode.
See the OpenOptions::open
method for more details.
Errors
This function will return an error if path
does not already exist.
Other errors may also be returned according to OpenOptions::open
.
pub fn create<P: AsRef<Path>>(path: P) -> Result<SgxFile>
[src]
Opens a file in write-only mode.
This function will create a file if it does not exist, and will truncate it if it does.
pub fn open_ex<P: AsRef<Path>>(
path: P,
key: &sgx_key_128bit_t
) -> Result<SgxFile>
[src]
path: P,
key: &sgx_key_128bit_t
) -> Result<SgxFile>
pub fn create_ex<P: AsRef<Path>>(
path: P,
key: &sgx_key_128bit_t
) -> Result<SgxFile>
[src]
path: P,
key: &sgx_key_128bit_t
) -> Result<SgxFile>
pub fn is_eof(&self) -> bool
[src]
pub fn clearerr(&self)
[src]
pub fn clear_cache(&self) -> Result<()>
