generic-new
A derive macro which generates an ergonomic constructor with shortcuts for certain types.
use generic_new::GenericNew;
#[derive(GenericNew)]
struct Foo {
s: String, // -> impl AsRef<str>
v: Vec<usize>, // -> impl IntoIterator<Item = usize>
i: Vec<String>, // -> impl IntoIterator<Item = impl AsRef<str>>
p: PathBuf, // -> impl AsRef<Path>
#[generic_new(ignore)]
o: String, // Turn off magic conversion for some fields
#[generic_new(ty = impl Into<usize>, converter = |u|Into::into(u))]
u: usize, // Custom converters are supported
}
Foo::new(
"hello",
[1, 2, 3],
["a", "b", "c"],
"path/to/foo",
String::from("world"),

);
