E0435: Reserved function name
| Code | Category | Stability |
|---|---|---|
E0435 | Struct and enum | Permanent |
Explanation
A user-defined function has a name reserved for a runtime or code-generation helper. Rue reserves every name beginning with __rue_, the entry-point symbols _start and _main, and the fixed memory-routine names memcpy, memmove, memset, memcmp, and bcmp so user code cannot collide with compiler- or runtime-emitted symbols.
Likely cause
The function was given an internal-looking name or the name of a platform entry point or memory routine. Rename the function to an ordinary user identifier that is outside the reserved set.
Examples
Define a reserved runtime-helper name
fn __rue_helper() -> i32 { 42 }
fn main() -> i32 { 0 }
Use an ordinary user function name
fn rue_helper() -> i32 { 42 }
fn main() -> i32 { rue_helper() }
