E0410: Duplicate method
| Code | Category | Stability |
|---|---|---|
E0410 | Struct and enum | Permanent |
Explanation
A struct definition declares more than one method or associated function with the same name. Both declaration forms share the struct's callable-member name space, so each callable member name must be unique within that struct; changing parameter types, count, return type, or mode does not create an overload.
Likely cause
A method or associated function was copied, renamed incompletely, or generated twice in one struct definition. Remove one declaration or give the callable members distinct names.
Examples
Duplicate method declaration
struct Point {
x: i32,
fn value(self) -> i32 { self.x }
fn value(self) -> i32 { self.x }
}
fn main() -> i32 { 0 }
Give each method a unique name
struct Point {
x: i32,
fn value(self) -> i32 { self.x }
fn doubled(self) -> i32 { self.x * 2 }
}
fn main() -> i32 { 0 }
