Attempted to dereference a variable which cannot be dereferenced.
Erroneous code example:
let y = 0u32; *y; // error: type `u32` cannot be dereferenced
Only types implementing std::ops::Deref
can be dereferenced (such as &T
). Example:
let y = 0u32; let x = &y; // So here, `x` is a `&u32`, so we can dereference it: *x; // ok!
