rustExample of struct public field in Rust
A struct public field in Rust is a field of a struct that is accessible outside of the struct. This allows the struct to be used in a variety of ways, such as passing data between functions or creating a public API.
Example code
struct MyStruct {
pub field: i32,
}
fn main() {
let my_struct = MyStruct { field: 5 };
println!("{}", my_struct.field);
}
Output example
5
Code explanation
struct MyStruct {
: This line declares a new struct calledMyStruct
.pub field: i32,
: This line declares a public field calledfield

.let my_struct = MyStruct { field: 5 };
: This line creates a new instance ofMyStruct
and assigns the value5
to thefield
field.println!("{}", my_struct.field);
