Struct ruby_marshal::ValueArena

pub struct ValueArena { /* private fields */ }

An arena of Ruby values.

Implementations

impl ValueArena

pub fn new() -> Self

Make a new empty ValueArena.

The root node is nil.

pub fn root(&self) -> ValueHandle

Get the root ValueHandle.

pub fn replace_root<H>(&mut self, new_root: H) -> ValueHandle

where H: Into<ValueHandle>,

Replace the current root, returning the old root.

pub fn get<H>(&self, handle: H) -> Option<&Value>

where H: Into<ValueHandle>,

Get a reference to the Value denoted by the given ValueHandle.

pub fn get_symbol( &self, handle: TypedValueHandle<SymbolValue>, ) -> Option<&SymbolValue>

Get a reference to the SymbolValue denoted by the given TypedValueHandle.

Panics

Panics if the value is not a SymbolValue.

pub fn create_nil(&mut self) -> TypedValueHandle<NilValue>

Create an orphan Nil value and return the handle.

pub fn create_bool(&mut self, value: bool) -> TypedValueHandle<BoolValue>

Create an orphan Bool value and return the handle.

pub fn create_fixnum(&mut self, value: i32) -> TypedValueHandle<FixnumValue>

Create an orphan Fixnum value and return the handle.

pub fn create_symbol(&mut self, value: Vec<u8>) -> TypedValueHandle<SymbolValue>

Create an orphan Symbol value and return the handle.

If a symbol with this name already exists in this arena, it is returned instead of creating a new symbol.

pub fn create_new_symbol( &mut self, value: Vec<u8>, ) -> TypedValueHandle<SymbolValue>

Create a new orphan Symbol value and return the handle.

pub fn create_array( &mut self, value: Vec<ValueHandle>, ) -> TypedValueHandle<ArrayValue>

Create an orphan Array value and return the handle.

pub fn create_hash( &mut self, value: Vec<(ValueHandle, ValueHandle)>, default_value: Option<ValueHandle>, ) -> TypedValueHandle<HashValue>

Create an orphan Hash value and return the handle.

pub fn create_object( &mut self, name: TypedValueHandle<SymbolValue>, instance_variables: Vec<(TypedValueHandle<SymbolValue>, ValueHandle)>, ) -> TypedValueHandle<ObjectValue>

Create an orphan Object value and return the handle.

pub fn create_string(&mut self, value: Vec<u8>) -> TypedValueHandle<StringValue>

Create an orphan String value and return the handle.

pub fn create_user_defined( &mut self, name: TypedValueHandle<SymbolValue>, value: Vec<u8>, ) -> TypedValueHandle<UserDefinedValue>

Create an orphan UserDefined value and return the handle.
