Types

type ArchInfo

type ArchInfo int

ArchInfo represents an architecture returned by Architecture().

	I386 ArchInfo = iota
	// Amd64 represents the x86_64 (64-bit) architecture.
	Amd64
	// Arm represents the ARM architecture.
	Arm
	// UnknownArch represents an unknown architecture.
	UnknownArch
)

func Architecture
