Implementations

impl MinimalRuntime

pub fn default_allocator(&self) -> &'static dyn GlobalAlloc

pub fn exit(&self, code: i32) -> !

pub fn abort(&self) -> !

pub fn pre_main_hook(&self) -> Option<i32>

pub fn post_main_hook(&self)

pub fn runtime_entry( &self, rt_info: *const RuntimeInfo, std_entry: unsafe extern "C-unwind" fn(_: BasicAux) -> BasicReturn, ) -> !

Called from _start to initialize the runtime and pass control to the Rust stdlib.

pub fn sysinfo(&self) -> SystemInfo

pub fn get_random(&self, buf: &mut [u8]) -> usize

impl MinimalRuntime

pub fn get_image_info(&self, id: loaded_image_id) -> Option<loaded_image>

pub fn iterate_phdr(&self, f: &mut dyn FnMut(dl_phdr_info) -> c_int) -> c_int

impl MinimalRuntime

pub fn open(&self, path: &str) -> Result<RawFd, OpenError>

pub fn read(&self, fd: RawFd, buf: &mut [u8]) -> Result<usize, IoError>

pub fn fd_pread( &self, fd: RawFd, off: Option<u64>, buf: &mut [u8], flags: IoFlags, ) -> Result<usize, IoError>

pub fn fd_pwrite( &self, fd: RawFd, off: Option<u64>, buf: &[u8], flags: IoFlags, ) -> Result<usize, IoError>

pub fn fd_pwritev( &self, fd: RawFd, off: Option<u64>, buf: &[io_vec], flags: IoFlags, ) -> Result<usize, IoError>

pub fn fd_preadv( &self, fd: RawFd, off: Option<u64>, buf: &[io_vec], flags: IoFlags, ) -> Result<usize, IoError>

pub fn fd_get_info(&self, fd: RawFd) -> Option<fd_info>

pub fn write(&self, fd: RawFd, buf: &[u8]) -> Result<usize, IoError>

pub fn close(&self, fd: RawFd) -> Option<()>

pub fn seek(&self, fd: RawFd, pos: SeekFrom) -> Result<usize, IoError>

impl MinimalRuntime

pub fn map_object( &self, id: ObjID, flags: MapFlags, ) -> Result<ObjectHandle, MapError>

pub fn release_handle(&self, handle: *mut object_handle)

pub fn map_two_objects( &self, in_id_a: ObjID, in_flags_a: MapFlags, in_id_b: ObjID, in_flags_b: MapFlags, ) -> Result<(ObjectHandle, ObjectHandle), MapError>

Map two objects in sequence, useful for executable loading. The default implementation makes no guarantees about ordering.

pub fn sleep(&self, duration: Duration)

pub fn join(&self, id: u32, timeout: Option<Duration>) -> Result<(), JoinError>

Trait Implementations

impl Default for MinimalRuntime

fn default() -> MinimalRuntime

Returns the “default value” for a type.
