Implementations

impl ValuePtr

pub fn into_string(self, vm: &Vm) -> Result<Slot, StackError>

Try to coerce value reference into an array.

pub fn into_array(self, vm: &Vm) -> Result<Slot, StackError>

Try to coerce value reference into an array.

pub fn into_object(self, vm: &Vm) -> Result<Slot, StackError>

Try to coerce value reference into an object.

pub fn into_external(self, vm: &Vm) -> Result<Slot, StackError>

Try to coerce value reference into an external.

pub fn value_type(&self, vm: &Vm) -> Result<ValueType, StackError>

Get the type information for the current value.

pub fn type_info(&self, vm: &Vm) -> Result<ValueTypeInfo, StackError>

Get the type information for the current value.

Trait Implementations

impl Clone for ValuePtr

fn clone(&self) -> ValuePtr

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for ValuePtr

impl Debug for ValuePtr

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for ValuePtr

fn default() -> Self

Returns the "default value" for a type.

impl<'de> Deserialize<'de> for ValuePtr

Deserialize implementation for value pointers.

Warning: This only works if a Vm is accessible through tls, like by being set up with tls::inject_vm or tls::InjectVm.

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error> where
    D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl FromValue for ValuePtr

fn from_value(value: ValuePtr, _: &mut Vm) -> Result<Self, StackError>

Try to convert to the given type, from the given value.

impl PartialEq<ValuePtr> for ValuePtr

fn eq(&self, other: &ValuePtr) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ValuePtr) -> bool

This method tests for !=.

impl Serialize for ValuePtr

Serialize implementation for value pointers.

Warning: This only works if a Vm is accessible through tls, like by being set up with tls::inject_vm or tls::InjectVm.

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error> where
    S: Serializer, 

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for ValuePtr

impl ToValue for ValuePtr

fn to_value(self, _vm: &mut Vm) -> Result<ValuePtr, StackError>

Convert into a value.
