go_vet100%

go vet examines Go source code and reports suspicious constructs, such as Printf calls whose arguments do not align with the format string.

No problems detected. Good job!

gocyclo94%

Gocyclo calculates cyclomatic complexities of functions in Go source code. The cyclomatic complexity of a function is calculated according to the following rules: 1 is the base complexity of a function +1 for each 'if', 'for', 'case', '&&' or '||' Go Report Card warns on functions with cyclomatic complexity > 15.
