Chapter 4 - Section Serialization and Deserialization - Cargo.toml dependency for serde needs text for feature "derive"

[glafrance]

In chapter 4, in the section entitled "Serialization and Deserialization", it indicates we must add this to our dependencies in Cargo.toml:

[dependencies]
serde = "1.0"
serde_json = "1.0"

But for the code to run it should be:

[dependencies]
serde = { version = "1.0", features = ["derive"] }
serde_json = "1.0"

Without these changes cargo build gives errors, such as:

error: cannot find derive macro Serialize in this scope
--> src/main.rs:4:10
