Implementations

impl WasiCtxBuilder

pub fn new() -> Self

pub fn set_stdin(self, stdin: impl InputStream + 'static) -> Self

pub fn set_stdout(self, stdout: impl OutputStream + 'static) -> Self

pub fn set_stderr(self, stderr: impl OutputStream + 'static) -> Self

pub fn inherit_stdin(self) -> Self

pub fn inherit_stdout(self) -> Self

pub fn inherit_stderr(self) -> Self

pub fn inherit_stdio(self) -> Self

pub fn set_env(self, env: &[(impl AsRef<str>, impl AsRef<str>)]) -> Self

pub fn push_env(self, k: impl AsRef<str>, v: impl AsRef<str>) -> Self

pub fn set_args(self, args: &[impl AsRef<str>]) -> Self

pub fn push_arg(self, arg: impl AsRef<str>) -> Self

pub fn push_preopened_dir( self, dir: Dir, perms: DirPerms, file_perms: FilePerms, path: impl AsRef<str> ) -> Self

pub fn set_secure_random(self) -> Self

Set the generator for the secure random number generator.

This initializes the random number generator using cap_rand::thread_rng.

pub fn set_secure_random_to_custom_generator( self, random: impl RngCore + Send + Sync + 'static ) -> Self

Set the generator for the secure random number generator to a custom generator.

This function is usually not needed; use set_secure_random to install the default generator, which is intended to be sufficient for most use cases.

Guest code may rely on this random number generator to produce fresh unpredictable random data in order to maintain its security invariants, and ideally should use the insecure random API otherwise, so using any prerecorded or otherwise predictable data may compromise security.

pub fn set_insecure_random( self, insecure_random: impl RngCore + Send + Sync + 'static ) -> Self

pub fn set_insecure_random_seed(self, insecure_random_seed: u128) -> Self

pub fn set_wall_clock(self, clock: impl HostWallClock + 'static) -> Self

pub fn set_monotonic_clock( self, clock: impl HostMonotonicClock + 'static ) -> Self

pub fn build(self, table: &mut Table) -> Result<WasiCtx, Error>
