}

Fields

fds: HashMap<u32, FdEntry, RandomState>

args: Vec<CString>

env: Vec<CString>

Methods

impl WasiCtx

pub fn new<S>(args: impl Iterator<Item = S>) -> Result<WasiCtx, u16> where
    S: AsRef<str>, 

Make a new WasiCtx with some default settings.

• File descriptors 0, 1, and 2 inherit stdin, stdout, and stderr from the host process.

• Environment variables are inherited from the host process.

To override these behaviors, use WasiCtxBuilder.

pub fn contains_fd_entry(&self, fd: u32) -> bool

pub fn get_fd_entry(
    &self,
    fd: u32,
    rights_base: u64,
    rights_inheriting: u64
) -> Result<&FdEntry, u16>

pub fn get_fd_entry_mut(
    &mut self,
    fd: u32,
    rights_base: u64,
    rights_inheriting: u64
) -> Result<&mut FdEntry, u16>

pub fn insert_fd_entry(&mut self, fe: FdEntry) -> Result<u32, u16>

Trait Implementations
