Derive debug extras

More customisable #[derive(Debug)]

Adds three options:

#[debug_single_tuple_inline]

use derive_debug_extras::DebugMore;

#[derive(DebugMore)]
#[debug_single_tuple_inline]
struct A(pub u32);

Verbose debugging on A retains single line under verbose.

e.g. for println!("{:#?}", vec![A(123), A(145), A(125),])

// With #[debug_single_tuple_inline]
[
    A(123),
    A(145),
    A(125),
]
// Without #[debug_single_tuple_inline]
[
    A(
        123
    ),
    A(
        145
    ),
    A(
        125
    ),
]

#[debug_single_tuple_inline] works on enums as well. Will fail for unnamed tuples with more than one field or named fields.

#[debug_ignore]

#[derive(DebugMore)]
struct C {
    x: u32,
    #[debug_ignore]
    _y: bool,
}

Ignores the _y field when debugging

#[debug_as_display]

#[derive(DebugMore)]
struct D {
    #[debug_as_display]
    x: String,
}

Prints the x field out as if it was formatted with Display

e.g. for println!("{:#?}", D("Hello World".to_string()))

// With #[debug_as_display]
D(Hello World)
// Without #[debug_as_display]
D("Hello World")
