Fields

rights: Rights

rights_inheriting: Rights

flags: Fdflags

offset: Arc<AtomicU64>

open_flags: u16

Flags that determine how the Fd can be used.

Used when reopening a VirtualFile during [WasiState] deserialization.

inode: InodeGuard

is_stdio: bool

Implementations

impl Fd

pub const READ: u16 = 1u16

This Fd can be used with read system calls.

pub const WRITE: u16 = 2u16

This Fd can be used with write system calls.

pub const APPEND: u16 = 4u16

This Fd can append in write system calls. Note that the append permission implies the write permission.

pub const TRUNCATE: u16 = 8u16

This Fd will delete everything before writing. Note that truncate permissions require the write permission.

This permission is currently unused when deserializing [WasiState].

pub const CREATE: u16 = 16u16

This Fd may create a file before writing to it. Note that create permissions require write permissions.

This permission is currently unused when deserializing [WasiState].

Trait Implementations

fn clone(&self) -> Fd

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Fd

fn fmt(&self, f: &mut Formatter<'_>) -> Result
