§TRL - type reflection library

This library provides auto generation of some common methods based on Rust macros

All future examples will use this test struct:

struct User {
    id: u32,
    name: String,
    email: String,

    // public fields are ignored by default
    pub phone_number: u64,
}

This library contains 2 types of macros:

Both of them have addictional arguments

Struct level macros are: getters and setters. They generates getters/setters for all the fields of the struct They have common arguments:

#[derive(trl)]
#[getters(include=[name, email])]
#[setters(include=[name, email])]
struct Test {/* ... */}

Would generate getters/setters for b and c fields.

exclude=[…] - generate getters/setters for all fields except the listed. For example

#[derive(trl)]
#[getters(exclude=[a, b])]
#[setters(exclude=[a, b])]
struct Test { /* ... */ }

Would generate getters/setters only for the c field.

pub - include public fields. By default public fields are ignored, but you can specify the pub argument to generate getters/setters for them too
prefix=… - generates getters/setters with specified prefix. For example

#[derive(trl)]
#[getters(prefix=get_)]
#[setters(prefix=set_)]
struct Test { /* ... */ }

Would generate getters:

Default value for getters is empty string, and for setters is set_

Field level macros are get and set. They generates a getter/setter for a single field. They have common arguments:
