Provides a newtype wrapper MaybeString
and its slice counterpart MaybeStr
that represents a byte vector that may be a valid UTF-8 string.
These wrappers are useful when working with data that may be a valid UTF-8 string and you want to delay or conditionally skip its conversion to the string.
They are also useful for debugging data that may be displayed as a string.
The Debug
output will provide string representation when the wrapped byte vector is a valid UTF-8 string.
```rust use maybe_string::MaybeString;
// invalid UTF-8 bytes let ms = MaybeString(vec![0, 159, 146, 150]); assert_eq!(&format!("{:?}", ms), "[00, 9f, 92, 96]");
// valid UTF-8 bytes let ms = MaybeString(vec![240, 159, 146, 150]); assert_eq!(&format!("{:?}", ms), "\"💖\""); ```
```rust use maybe_string::MaybeString;
// invalid UTF-8 bytes let ms = MaybeString(vec![0, 159, 146, 150]); asserteq!(ms.intostring(), Err(vec![0, 159, 146, 150]));
// valid UTF-8 bytes let ms = MaybeString(vec![240, 159, 146, 150]); asserteq!(ms.intostring(), Ok("💖".to_string())); ```
