pub struct EnvConfig { /* private fields */ }

Expand description

Configuration structure for environments.

Implementations

source

impl EnvConfig

source

pub fn new(max_memory: usize, max_fuel: Option<u64>) -> Self

Create a new environment configuration.

source

pub fn allow_namespace<S: Into<String>>(&mut self, namespace: S)

Allow a WebAssembly host function namespace to be used with this config.

source

pub fn preopened_dirs(&self) -> &[String ]

source

source

pub fn plugins(&self) -> &Vec<Plugin>ⓘ
Notable traits for Vec<u8, A>
`impl<A> Write for Vec<u8, A> where A: Allocator,`

source

pub fn add_plugin(&mut self, module: Vec<u8>) -> Result<()>

Add module as a plugin that will be used on all processes in the environment.

Plugins are just regular WebAssembly modules that can define specific hooks inside the runtime to modify other modules that are dynamically loaded inside the environment or spawn environment bound processes.
