typeinfo
The typeinfo
crate provides access to type information for POD (plain old data)
types at runtime.
Examples
Defining reflectable struct types only requires wrapping the struct definition in
the def!
macro:
#[use_macro]
extern crate typeinfo;
use typeinfo::TypeInfo;
def! {
#[derive(Debug)]
pub struct Color { r: u16, g: u16, b: u16, }
#[derive(Debug)]
#[repr(packed)]
pub struct Palette {
monochrome: bool,
colors: [Color; 16]
}
}
fn main() {
println!("{:#?}", Palette::type_info());
}
Output (whitespace formatted):
Compound([
Field { ty: Bool, name: "monochrome", offset: 0 },
Field {
ty: Array(
Compound([
Field { ty: UInt16, name: "r", offset: 0 },
Field { ty: UInt16, name: "g", offset: 2 },
Field { ty: UInt16, name: "b", offset: 4 }
], 6),
16),
name: "colors",
offset: 1
}
], 97)
