Trait Eval

pub trait Eval {
    type Value: Value;
    type Error;

    // Required methods
    fn eval(&mut self, code: &[u8]) -> Result<Self::Value, Self::Error>;
    fn eval_os_str(&mut self, code: &OsStr) -> Result<Self::Value, Self::Error>;
    fn eval_file(&mut self, file: &Path) -> Result<Self::Value, Self::Error>;
}

Execute code and retrieve its result.

Required Associated Types

type Value: Value

Concrete type for return values from eval.

type Error

Concrete error type for eval functions.

Required Methods

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

Eval code on the Artichoke interpreter using the current parser context.

Errors

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

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

Available on crate feature std only.

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

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.

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

Available on crate feature std only.

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

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.
