sensible

This is a crate for a more configurable derive macro to derive an implementation for [Default][]. Rust's [std::default][] module provides a derive implementation, but for structs, it requires that:

• Every member on the struct implement Default.
• Every member on the struct must use the Default implementation.

This is fine for many cases, but consider the case of a large struct where just one or two fields should default to something other than their type's Default implementation: now you have to implement the whole thing.

sensible provides a configurable derive macro that allows giving certain fields alternate default values.

Example

```rs use sensible::Default;

[derive(Default)]

struct Foo { a: u32, // default value: 0

#[default(42)] b: u32, // default value: 42 } ```
