pub trait DataModel<T: ProtocolModel>

Expand description

The trait of the data models, which is used to read/write the typed data from/input Plumber pipe port.

A data model is created when the exec function have created the type instance object and bufferred the typed data into the type instance object. This is the Rust wrapper for the type instance object from libpstd.

This trait is usually implemented by the macro protodef!. It’s rare that you have to manually implement the data model class. See the documentaiton for protodef! macro for details.

Required Methods§

Source

fn new_data_model(model: Rc<T>, type_inst: TypeInstanceObject) -> Self

Create the new data type model

  • model: The smart pointer for the data model
  • type_inst: The data instance object created for current task

Returns the newly created data model object

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
