Struct sgx_tprotected_fs::OpenOptions

pub struct OpenOptions(_);

Options and flags which can be used to configure how a file is opened.

This builder exposes the ability to configure how a SgxFile is opened and what operations are permitted on the open file. The SgxFile::open and SgxFile::create methods are aliases for commonly used options using this builder.
