Expand description
A boxed Ruby value owned by the interpreter.
Value
is equivalent to an RValue
in MRI or mrb_value
in mruby.

Required Methods§
sourcefn funcall(
&self,
interp: &mut Self::Artichoke,
func: &str,
args: &[Self::Arg],
block: Option<Self::Block>,
) -> Result<Self::Value, Self::Error>
fn funcall( &self, interp: &mut Self::Artichoke, func: &str, args: &[Self::Arg], block: Option<Self::Block>, ) -> Result<Self::Value, Self::Error>
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.
sourcefn respond_to(
&self,
interp: &mut Self::Artichoke,
method: &str,
) -> Result<bool, Self::Error>
fn respond_to( &self, interp: &mut Self::Artichoke, method: &str, ) -> Result<bool, Self::Error>
sourcefn inspect(&self, interp: &mut Self::Artichoke) -> Vec<u8>
fn inspect(&self, interp: &mut Self::Artichoke) -> Vec<u8>
Call #inspect
on this Value
.
This function can never fail.
sourcefn to_s(&self, interp: &mut Self::Artichoke) -> Vec<u8>
fn to_s(&self, interp: &mut Self::Artichoke) -> Vec<u8>
Call #to_s
on this Value
.
This function can never fail.
sourcefn ruby_type(&self) -> Ruby
fn ruby_type(&self) -> Ruby
Return this values Rust-mapped type tag.
Provided Methods§
sourcefn try_convert_into<T>(self, interp: &Self::Artichoke) -> Result<T, Self::Error>
fn try_convert_into<T>(self, interp: &Self::Artichoke) -> Result<T, Self::Error>
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.
sourcefn try_convert_into_mut<T>(
self,
interp: &mut Self::Artichoke,
) -> Result<T, Self::Error>
fn try_convert_into_mut<T>( self, interp: &mut Self::Artichoke, ) -> Result<T, Self::Error>
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.
