The README suggests adding futures = "1.0" into Cargo.toml, but that doesn't seem to exist

[atroche]

From Cargo.toml:

[dependencies]
anyhow = "1.0"
futures = "1.0"
tarpc = { version = "0.27", features = ["tokio1"] }
tokio = { version = "1.0", features = ["macros"] }

❯ cargo build
    Updating crates.io index
error: failed to select a version for the requirement `futures = "^1.0"`
candidate versions found which didn't match: 0.3.17, 0.3.16, 0.3.15, ...
location searched: crates.io index

Fixed with specifying futures = 0.3 instead, which is also what exampe-service uses.
