Expand description

A boxed Ruby value owned by the interpreter.

Value is equivalent to an RValue in MRI or mrb_value in mruby.

Associated Types

Concrete type for Artichoke interpreter.

Concrete type for arguments passed to funcall.

Concrete type for results from funcall.

Concrete type for blocks passed to funcall.

Concrete error type for funcall errors.

Required methods

Call a method on this Value with arguments and an optional block.

Errors

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

If a TryConvert conversion fails, then an error is returned.

Call #freeze on this Value.

Errors

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

Call #frozen? on this Value.

Whether self is nil

Whether self responds to a method.

Equivalent to invoking #respond_to? on this Value.

Errors

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

Call #inspect on this Value.

This function can never fail.

Call #to_s on this Value.

This function can never fail.

Return this values Rust-mapped type tag.

Provided methods

Consume self and try to convert self to type T using a TryConvert conversion.

Errors

If a TryConvert conversion fails, then an error is returned.

Consume self and try to convert self to type T using a TryConvertMut conversion.

Errors

If a TryConvertMut conversion fails, then an error is returned.
