}

Fields

rights: Rights

rights_inheriting: Rights

flags: Fdflags

offset: u64

open_flags: u16

Flags that determine how the Fd can be used.

inode: Inode

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.
