Rust Conversion traits From
Example
Rust's From trait is a general-purpose trait for converting between types. For any two types TypeA and TypeB,
impl From<TypeA> for TypeB
indicates that an instance of TypeB is guaranteed to be constructible from an instance of TypeA. An implementation of From looks like this:
struct TypeA {
a: u32,
}
struct TypeB {
b: u32,
}
impl From<TypeA> for TypeB {
fn from(src: TypeA) -> Self {
TypeB {
b: src.a,
}
}
}
