Consider using rust2rpm
The rust2rpm tool, available as a Fedora package or at https://pagure.io/fedora-rust/rust2rpm, automates many of these steps. Try rust2rpm $crate first before trying to write a specfile by hand.

Naming

Dependencies

Packages MUST have BuildRequires: rust-packaging.

Automatic Requires/Provides

rust-packaging automatically creates Requires/Provides based on %cargo_registry/*/Cargo.toml files. Automatic provides create crate($name) = $version and crate($name/$feature) = $version for each "feature" crate provides. Automatic requirements take all this into account and create For example, syn = { version = "0.11", features = ["visit"] } becomes Requires: ((crate(syn) >= 0.11.0 with crate(syn) < 0.12.0) with crate(syn/visit)).

BuildRequires

Packagers MUST specify all BuildRequires according to the definition in Cargo.toml, for example: 

[dependencies]
atty = "0.2.2"
[build-dependencies]
clap = "2.24.1"

should become to 

# [dependencies]
BuildRequires:  (crate(atty) >= 0.2.2 with crate(atty) < 0.3.0)
# [build-dependencies]
BuildRequires:  (crate(clap) >= 2.24.1 with crate(clap) < 3.0.0)

Versions

Packagers SHOULD try to use latest version of dependent crates even if it requires patching of crate (along with sending Pull Request to upstream) to reduce maintenance burden.

ExclusiveArch

All rust packages MUST have ExclusiveArch: %{rust_arches}.

Others

Packagers MUST run %cargo_prep to prepare configuration for further cargo invocations (sets up RUSTFLAGS and all other stuff).

Nightly, Other Platforms, etc. crates

Packagers MUST NOT package crates which do not work with distribution. Packagers MUST patch packages which use such dependencies, for example:
