Crate proffer

Proffer is a code generation library to create code from other data structures such as JSON or any other reason where generating raw source code is required.

Example

use proffer::*;

let ipl = Impl::new("That")
    .add_generic(Generic::new("T").add_trait_bounds(vec!["ToString"]).to_owned())
    .add_function(
        Function::new("foo")
            .set_is_pub(true)
            .add_parameter(Parameter::new("bar1", "T"))
            .add_parameter(Parameter::new("bar2", "S"))
            .set_return_ty("T")
            .add_generic(Generic::new("S"))
            .set_body("bar1")
            .to_owned()
    ).to_owned();

let expected = r#"
    impl<T> That<T>
        where
            T: ToString,
    {
        pub fn foo<S>(bar1: T, bar2: S) -> T
            where
                S: ,
        {
            bar1
        }
    }
"#;

let src_code = ipl.generate();
println!("{}", &src_code);

assert_eq!(
    norm_whitespace(expected),
    norm_whitespace(&src_code)
)

Modules

associated_types_gen

Create a associated type for traits and trait implementations.

enum_gen

Create enum objects

field_gen

Field generation module, represents single fields within a struct

function_gen

Function pieces, specifically Function which is composed of FunctionSignature and FunctionBody. Naturally, a Function can be used as a “method” for another object, by specifying self (or some variant of it) as the first Parameter to a Function object.

generics_gen

Create a single or collection of generics/trait bounds for functions and other objects.

impl_gen

Create impl blocks for functions, traits, and other objects.

module_gen

Create a Module which can hold any number of other SrcCode elements.

struct_gen

Create a struct object.

trait_gen

Create a trait definition

traits

Trait(s) specific to code generation objects within this crate.

Functions

norm_whitespace

Helper function throughout tests and documentation for comparing expected source code generated.
