A boxed Ruby value owned by the interpreter.

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

Required methods

pub fn funcall(
    &self,
    interp: &mut Self::Artichoke,
    func: &str,
    args: &[Self::Arg],
    block: Option<Self::Block>
) -> Result<Self::Value, Self::Error>[src]

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.

pub fn freeze(
    &mut self,
    interp: &mut Self::Artichoke
) -> Result<(), Self::Error>[src]

Call #freeze on this Value.

Errors

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

pub fn is_frozen(&self, interp: &mut Self::Artichoke) -> bool[src]

Call #frozen? on this Value.

pub fn is_nil(&self) -> bool[src]

Whether self is nil

pub fn respond_to(
    &self,
    interp: &mut Self::Artichoke,
    method: &str
) -> Result<bool, Self::Error>[src]

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.

pub fn inspect(&self, interp: &mut Self::Artichoke) -> Vec<u8, Global>[src]

Call #inspect on this Value.

This function can never fail.

pub fn to_s(&self, interp: &mut Self::Artichoke) -> Vec<u8, Global>[src]

Call #to_s on this Value.

This function can never fail.

pub fn ruby_type(&self) -> Ruby[src]

Return this values Rust-mapped type tag.

Provided methods

pub fn try_into<T>(self, interp: &Self::Artichoke) -> Result<T, Self::Error> where
    Self::Artichoke: TryConvert<Self, T>,
    <Self::Artichoke as TryConvert<Self, T>>::Error == Self::Error, [src]

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.

pub fn try_into_mut<T>(
    self,
    interp: &mut Self::Artichoke
) -> Result<T, Self::Error> where
    Self::Artichoke: TryConvertMut<Self, T>,
    <Self::Artichoke as TryConvertMut<Self, T>>::Error == Self::Error, [src]

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.
