Crate trimmer_derive

Expand description

Derive implementation for trimmer template engine

This crate allows to derive trimmer::Variable trait.

Currently it supports two kinds of structures, a tuple structure with a single field (i.e. a newtype pattern):

extern crate trimmer;
#[macro_use] extern crate trimmer_derive;

#[derive(Debug, Variable)]
struct Variable(String);

In this case, all methods of the variable implementation will be forwarded to the enclosed type (and it must implement Variable)

And for regular structures with named patterns:

extern crate trimmer;
#[macro_use] extern crate trimmer_derive;

#[derive(Debug, Variable)]
struct Point {
    x: u32,
    y: u32,
}

In this case, Point will implement attr method resolving x and y. All fields must implement Variable trait themselves.
