Required methods

pub fn eval(&mut self, code: &[u8]) -> Result<Self::Value, Self::Error>[src]

Eval code on the Artichoke interpreter using the current Context.

Errors

If an exception is raised on the interpreter, then an error is returned.

pub fn eval_os_str(&mut self, code: &OsStr) -> Result<Self::Value, Self::Error>[src]

Eval code on the Artichoke interpreter using the current Context when given code as an OsStr.

This trait method requires activating the std feature in artichoke-core.

Errors

If an exception is raised on the interpreter, then an error is returned.

If code cannot be converted to a &[u8] on the current platform, then an error is returned.

pub fn eval_file(&mut self, file: &Path) -> Result<Self::Value, Self::Error>[src]

Eval code on the Artichoke interpreter using a new file Context given a file path.

This trait method requires activating the std feature in artichoke-core.

Errors

If an exception is raised on the interpreter, then an error is returned.

If path does not exist or code cannot be read, an error is returned.
