def ==(other)

Is other equal to this platform? Two platforms are equal if they have the same CPU, OS and version.

@version == other.version
)
end
Does other match this platform? Two platforms match if they have the same CPU, or either has a CPU of ‘universal’, they have the same OS, and they have the same version, or either one has no version
Additionally, the platform will match if the local CPU is ‘arm’ and the other CPU starts with “armv” (for generic 32-bit ARM family support).
Of note, this method is not commutative. Indeed the OS ‘linux’ has a special case: the version is the libc name, yet while “no version” stands as a wildcard for a binary gem platform (as for other OSes), for the runtime platform “no version” stands for ‘gnu’. To be able to distinguish these, the method receiver is the gem platform, while the argument is the runtime platform.

def deconstruct_keys(keys)
{ cpu: @cpu, os: @os, version: @version }
end
Deconstructs the platform into a hash for pattern matching. Returns a hash with keys :cpu, :os, and :version.
Gem::Platform.new("x86_64-darwin-20").deconstruct_keys(nil) #=> { cpu: "x86_64", os: "darwin", version: "20" }
This enables hash pattern matching:
case Gem::Platform.new("x86_64-linux") in cpu: "x86_64", os: "linux" # Matches Linux on x86_64 end
