Traits for implicit coercion
⚓ Rust 📅 2025-06-16 👤 surdeus 👁️ 14I am to learn syntax... and typing .into() seems that I am missing some knowledge on Rust's way of code.
#[derive(Debug)]
pub struct A(isize);
impl From<isize> for A {
fn from(value: isize) -> Self {
A(value)
}
}
#[derive(Debug)]
pub struct B(isize);
// impl something here
fn main() {
let a: A = 32.into();
println!("A={:?}({})", a, a.0);
let b: B = 32; // so this is legal.
println!("B={:?}({})", b, b.0);
}
Is assigning b:B to 32 directly somehow possible?
