}Expand description
Read a single data item from input stream.
All types that implement this trait also implement ReadFrom.
§Errors
- If the input cannot be parsed into
T, ReadError::FromStrError is returned. - If the input is not valid UTF-8, ReadError::IOError is returned.
- If an I/O error occurs, ReadError::IOError is returned.

Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
