error[E0599]: `*const u8` doesn't implement `std::fmt::Display`
|
|
--> $DIR/suggest-convert-ptr-to-ref.rs:5:22
|
|
|
|
|
LL | println!("{}", z.to_string());
|
|
| ^^^^^^^^^ `*const u8` cannot be formatted with the default formatter
|

|
|
note: the method `to_string` exists on the type `&u8`
|
|
--> $SRC_DIR/alloc/src/string.rs:LL:COL

|
= note: you might want to use the unsafe method `<*const T>::as_ref` to get an optional reference to the value behind the pointer
|
|
= note: read the documentation for `<*const T>::as_ref` and ensure you satisfy its safety preconditions before calling it to avoid undefined behavior: https://doc.rust-lang.org/std/primitive.pointer.html#method.as_ref

= note: the following trait bounds were not satisfied:
|
|
`*const u8: std::fmt::Display`
|
|
which is required by `*const u8: ToString`
|
|
= note: in format strings you may be able to use `{:?}` (or {:#?} for pretty-print) instead
