Implementations

impl Value

pub fn as_bool(self) -> bool

pub fn type_name(self) -> &'static str

Typename of this value

pub fn is_float(self) -> bool

pub unsafe fn as_str<'a>(self) -> Option<&'a str>

Safety

Must be called with ptr obtained from a string_literal instruction, before the last clear!

The Vm that allocated the string must still be in memory!

Return

Returns None if the value is not a string, or points to an invalid string

pub unsafe fn as_table<'a>(self) -> Option<&'a CaoLangTable>

Safety

Must be called with ptr obtained from a vm , before the last clear!

The Vm that allocated the table must still be in memory!

Return

Returns None if the value is not a table, or points to an invalid table

pub fn as_int(self) -> Option<i64>

pub fn as_real(self) -> Option<f64>

pub fn is_obj(self) -> bool

pub fn is_integer(self) -> bool

pub fn is_null(self) -> bool
