Use uuid::Uuid data type with "serde" feature.

pub fsid: String, // Uuid Serialize and Deserialize isn't implemented for Uuid

At this line, it is stated that Serialize and Deserialize are not implemented for uuid::Uuid, and that is true only if the "serde" feature is not activated in Cargo.toml.

[dependencies]
uuid = { version = "0.6", features = ["serde", "v4"] }
