Struct Builder

pub struct Builder { /* private fields */ }

A builder for Runtime.

Implementations

impl Builder

pub fn sandboxed(self, sandboxed: bool) -> Self

Set whether the runtime is sandboxed.

When sandboxed, only a limited set of modules can be imported, and some built-in functions are disabled. This is useful for running untrusted code.

Allowed modules: json, decimal, re, math, datetime, time.

Disallowed builtins: breakpoint, exit, eval, help, input, open, print.

The default is false.

pub fn remove_symbol(self, symbol: &str) -> Self

Remove a symbol from builtins.

Examples

let builder = Runtime::builder().remove_symbol("__builtins__.eval");

pub fn build(self) -> Result<Runtime>

Build the Runtime.
