Struct InstanceConfig

pub struct InstanceConfig {
    pub stdin: PathBuf,
    pub stdout: PathBuf,
    pub stderr: PathBuf,
    pub bundle: PathBuf,
    pub namespace: String,
    pub containerd_address: String,
    pub config: Config,
}

Generic options builder for creating a wasm instance. This is passed to the Instance::new method.

Fields

stdin: PathBuf

Optional stdin named pipe path.

stdout: PathBuf

Optional stdout named pipe path.

stderr: PathBuf

Optional stderr named pipe path.

bundle: PathBuf

Path to the OCI bundle directory.

namespace: String

Namespace for containerd

containerd_address: String

GRPC address back to main containerd

config: Config

containerd runtime options config

Implementations

impl InstanceConfig

pub fn determine_rootdir( &self, runtime: impl AsRef<str> + Debug, ) -> Result<PathBuf, Error>

Determine the root directory for the container runtime.

If the bundle directory contains an options.json file, the root directory is read from the file. Otherwise, the root directory is determined by {DEFAULT_CONTAINER_ROOT_DIR}/{runtime}/{namespace}.

The default root directory is /run/containerd/<wasm engine name>/<namespace>.

pub fn open_stdin(&self) -> IoResult<File>

pub fn open_stdout(&self) -> IoResult<File>

pub fn open_stderr(&self) -> IoResult<File>
