Function std::default::default  [−][src]
pub fn default<T>() -> T where
    T: Default, Expand description
Return the default value of a type according to the Default trait.
The type to return is inferred from context; this is equivalent to
Default::default() but shorter to type.
For example:
#![feature(default_free_fn)]
use std::default::default;
#[derive(Default)]
struct AppConfig {
    foo: FooConfig,
    bar: BarConfig,
}
#[derive(Default)]
struct FooConfig {
    foo: i32,
}
#[derive(Default)]
struct BarConfig {
    bar: f32,
    baz: u8,
}
fn main() {
    let options = AppConfig {
        foo: default(),
        bar: BarConfig {
            bar: 10.1,
            ..default()
        },
    };
}
