You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: value.rs
    path of file: ./repos/prisma-engines/schema-engine/datamodel-renderer/src
    
    the code of the file until where you have to start completion: //! Common types needed in the configuration and datamodel.

mod array;
mod constant;
mod documentation;
mod env;
mod function;
mod text;

pub use array::Array;
pub use constant::Constant;
pub use documentation::Documentation;
pub use env::Env;
pub use
    
    fn fmt(&self, f: &mut fmt::Formatter<'_>) -> fmt::Result {
        match self {
            Value::Text(t) => f.debug_tuple("Text").field(t).finish(),
            Value::Constant(val) => {
                write!(f, "Constant({val})")
            }
            Value::Array(ary) => f.debug_tuple("Array").field(ary).finish(),
            Value::Function(fun) => f.debug_tuple("Function").field(fun).finish(),
            Value::Env(e) => f.debug_tuple("Env").field(e).finish(),
            Value::Bytes(Text(b)) => write!(f, "Bytes({b})"),
            Value::IndexOps(ops) => write!(f, "IndexOps({ops})"),
        }
    }
