Required Methods

fn options(flags: Open, mode: Mode) -> Self::Options

fn open(dir: BorrowedFd<'a>, path: &'a CStr, options: &'a Self::Options) -> Self

fn metadata(file: BorrowedFd<'a>, output: &'a mut Self::Metadata) -> Self

fn read( file: BorrowedFd<'a>, output: Value<&'a mut [MaybeUninit<u8>]>, offset: Offset, ) -> Self

fn write(file: BorrowedFd<'a>, input: Self::Buffer, offset: Offset) -> Self

fn write_current(file: BorrowedFd<'a>, input: Self::Buffer) -> Self

Writes at the owned descriptor’s current position, honoring O_APPEND.

fn sync(file: BorrowedFd<'a>, mode: Sync) -> Self

fn rename(dir: BorrowedFd<'a>, old: &'a CStr, new: &'a CStr) -> Self

fn unlink(dir: BorrowedFd<'a>, name: &'a CStr) -> Self

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
