Module ruststep::ast[][src]

Expand description

Abstract syntax tree for exchange structure

This module contains implementation of serde::Serialize and serde::Deserialize for AST structs.


Implementing a Deserializer page of serde manual says

The deserializer is responsible for mapping the input data into Serde’s data model by invoking exactly one of the methods on the Visitor that it receives.

serde::de::Deserializer trait is implemented for Parameter, Record, and SubSuperRecord. Be sure that this mapping is not only for espr-generated structs. This can be used with other Rust structs using serde_derive::Deserialize custom derive:

DATA section in STEP file

Entire exchange structure

A struct typed in EXPRESS schema, e.g. A(1.0, 2.0)

A set of Record mapping to complex entity instance, e.g. (A(1) B(2.0) C("3"))


Each line of data section

Name of an entity instance or a value

Primitive value type in STEP data
