Implementations

impl Value

#[must_use]pub fn new() -> Self

Create a new, empty Ruby value.

Alias for Value::default.

#[must_use]pub fn nil() -> Self

Create a nil Ruby Value.

#[must_use]pub fn inner(&self) -> mrb_value

The sys::mrb_value that this Value wraps.

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

Return this values Rust-mapped type tag.

#[must_use]pub fn pretty_name<'a>(&self, interp: &mut Artichoke) -> &'a str

#[must_use]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.

#[must_use]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: Int
) -> Result<Option<Range>, Exception>

pub fn implicitly_convert_to_int(
    &self,
