StructMapper

A library to help you generate code that mapped one struct to another.

Example

use structmapper::StructMapper;

struct From1 {
value: i32,
}

struct From2 {
value: i32,
}

struct From3 {
value: i32,
}

#[derive(StructMapper)]
#[struct_mapper(from_type = "From1")]
#[struct_mapper(from_type = "From2")]
#[struct_mapper(
from_type = "(From1, From2, From3)",
default_base = "{0}",
fields(
value = "{0.value} + {1.value} + {2.value}"
)
)]
struct To {
value: i32
}

let to = To::from(From1 { value: 1 });
assert_eq!(to.value, 1);

let to = To::from(From2 { value: 2 });
assert_eq!(to.value, 2);

let to = To::from((From1 { value: 1 }, From2 { value: 2 }, From3 { value: 3 }));
assert_eq!(to.value, 1 + 2 + 3);
