Struct wasi_common::WasiCtx

    pub args: Vec<CString>,
    pub env: Vec<CString>,
}

Fields

fds: HashMap<__wasi_fd_t, FdEntry>

args: Vec<CString>

env: Vec<CString>

Methods

impl WasiCtx

pub fn new<S: AsRef<str>>(
    args: impl Iterator<Item = S>
) -> Result<Self, __wasi_errno_t>

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: __wasi_fd_t) -> bool

pub fn get_fd_entry(
    &self,
    fd: __wasi_fd_t,
    rights_base: __wasi_rights_t,
    rights_inheriting: __wasi_rights_t
) -> Result<&FdEntry, __wasi_errno_t>

pub fn get_fd_entry_mut(
    &mut self,
    fd: __wasi_fd_t,
    rights_base: __wasi_rights_t,
    rights_inheriting: __wasi_rights_t
) -> Result<&mut FdEntry, __wasi_errno_t>

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