How to read a string?

[ritulahkar]

Is there any way to modify this nb::block!(serial.read()).void_unwrap() to read string. Or How to call String struct. Please help. I am a newbie.

Or How to call String struct.

String is not available on #![no_std] Rust because it requires an allocator. You can use the heapless::String type instead. It is backed by a fixed buffer instead of dynamically allocating memory at runtime.

You will then need to receive individual characters and write them into this string.
