The derive crate for bincode. Implements bincode::Encode
and bincode::Decode
.
This crate is roughly split into 2 parts:
Most of parsing is done in the src/parse/
folder. This will generate the following types:
Attributes
, not being used currentlyVisibility
, not being used currentlyDataType
either Struct
or Enum
, with the name of the data type being parsedGenerics
the generics part of the type, e.g. struct Foo<'a>
GenericConstraints
the "where" part of the typeGenerating the code implementation is done in either src/derive_enum.rs
and src/derive_struct.rs
.
This is supported by the structs in src/generate
. The most notable points of this module are:
StreamBuilder
is a thin but friendly wrapper around TokenStream
Generator
is the base type of the code generator. This has helper methods to generate implementations:
ImplFor
is a helper struct for a single impl A for B
construction. In this functions can be defined:
GenerateFnBody
is a helper struct for a single function in the above impl
. This is created with a callback to FnBuilder
which helps set some properties. GenerateFnBody
has a stream()
function which returns StreamBuilder
for the function.For additional derive testing, see the test cases in ../tests
For testing purposes, all generated code is outputted to the current target
folder, under file name <struct/enum name>_Encode.rs
and <struct/enum name>_Decode.rs
. This can help with debugging.
