Struct artichoke_backend::value::Value

pub struct Value(_);

Boxed Ruby value in the Artichoke interpreter.

Implementations

impl Value

pub fn new() -> Self

Create a new, empty Ruby value.

Alias for Value::default.

pub fn nil() -> Self

Create a nil Ruby Value.

pub fn is_unreachable(&self) -> bool

Whether a value is an interpreter-only variant not exposed to Ruby.

Some type tags like MRB_TT_UNDEF are internal to the mruby VM and manipulating them with the sys API is unspecified and may result in a segfault.

After extracting a sys::mrb_value from the interpreter, check to see if the value is unreachable a Fatal exception.

See: mruby#4460.

pub fn is_dead(&self, interp: &mut Artichoke) -> bool

Return whether this object is unreachable by any GC roots.

pub fn is_range( &self, interp: &mut Artichoke, len: i64 ) -> Result<Option<Range>, Error>
