Struct DynamicMessage 

pub struct DynamicMessage { /* private fields */ }

A looking_glass representation of a ProtocolBuffer message.

DynamicMessage allows users to create and read ProtocolBuffer messages at runtime. A DynamicMessage is created from a MessageView, but unlike a MessageView it owns its data. This means that DynamicMessages can be modified and re-encoded. In the name of efficiency string and byte, types are reference counted from their source.

Implementations

impl DynamicMessage

pub fn new<T: Tranche>(view: &MessageView<T>) -> Result<DynamicMessage, Error>

Builds a new DynamicMessage from a MessageView.

pub fn encoded_len(&self) -> usize

The length of the mesage once encoded

pub fn encode(&self, buf: &mut impl BufMut)

Encoded a DynamicMessage to the passed buffer

pub fn descriptor_name(&self) -> String

pub fn descriptor_database(&self) -> Arc<DescriptorDatabase>

Trait Implementations

impl Clone for DynamicMessage

fn clone(&self) -> DynamicMessage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DynamicMessage

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

Formats the value using the given formatter.

impl Instance<'static> for DynamicMessage

fn name(&self) -> SmolStr

Returns the name of a instance

fn as_inst(&self) -> &(dyn Instance<'static> + 'static)

impl PartialEq for DynamicMessage

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl StructInstance<'static> for DynamicMessage

fn get_value<'a>(&'a self, field: &str) -> Option<CowValue<'a, 'static>>

where 'static: 'a,

Returns a reference to a field in a struct

fn update<'a>( &'a mut self, update: &'a (dyn StructInstance<'static> + 'static), field_mask: Option<&FieldMask>, replace_repeated: bool, ) -> Result<(), Error>

Updates an instance based on the instance passed in. If a field mask is specified only the fields passed with the mask will be updated.

fn values<'a>(&'a self) -> HashMap<SmolStr, CowValue<'a, 'static>>

Returns a HashMap containing all the attributes of the instance.

fn boxed_clone(&self) -> Box<dyn StructInstance<'static> + 'static>

Returns a clone of the instance in a Box.

fn into_boxed_instance(self: Box<Self>) -> Box<dyn Instance<'static> + 'static>

Casts Self to a Box<dyn Instance>

impl Typed<'static> for DynamicMessage

fn ty() -> ValueTy

fn as_value<'a>(&'a self) -> Value<'a, 'static>

where 'static: 'a,
