Implementations

impl Value

pub fn class(&self, universe: &Universe) -> SOMRef<Class>

Get the class of the current value.

pub fn lookup_method( &self, universe: &Universe, signature: impl AsRef<str> ) -> Option<Rc<Method>>

Search for a given method for this value.

pub fn lookup_local(&self, name: impl AsRef<str>) -> Option<Self>

Search for a local binding within this value.

pub fn assign_local(&mut self, name: impl AsRef<str>, value: Self) -> Option<()>

Assign a value to a local binding within this value.

pub fn to_string(&self, universe: &Universe) -> String

Get the string representation of this value.

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl Hash for Value

fn hash<H: Hasher>(&self, hasher: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Value

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
