Derive trivial transformations between fields that are mostly unpacking and converting similarly-nemd fields from a source into a target. Example usage:
use namewise;
use std::collections::HashSet;
struct Source {
a: &'static str,
text: String,
numeric: i16,
truth: bool,
truths: Vec<bool>,
}
#[derive(namewise::From)]
#[namewise_from(from_type = "Source")]
struct Destination {
a: String,
text: String,
#[namewise_from(from_name = "numeric")]
number: i64,
#[namewise_from(collect)]
truths: HashSet<bool>,
}
This should be equivalent to:
use std::collections::HashSet;
struct Source {
a: &'static str,
text: String,
numeric: i16,
truth: bool,
truths: Vec<bool>,
}
struct Destination {
a: String,
text: String,
number: i64,
truths: HashSet<bool>,
}
impl From<Source> for Destination {
fn from(value: Source) -> Destination {
Destination {
a: value.a.into(),
text: value.text.into(),
number: value.numeric.into(),
truths: value.truths.into_iter().collect(),
}
}
}
