Minimum supported rust version
MSRV := 1.31.0
The crate will fail fast on any lower rustc (via a build.rs version check) and is also CI tested on this version, included both 2015 and 2018 edition external macro imports. A PR would be considered to backport the project to earlier rust versions, possibly as far back as 1.16.0 (log's current MSRV). Or consider lobbying for the inclusion of this feature in log itself.
With rustc 1.32.0+, one (but not more than one) trailing comma is properly accepted in -v macro calls. On 1.31.0, multiple trailing commas are erroneously accepted.
Compile time errors for misuse of -v macros (e.g. 0 arguments, 4 arguments, non-literal prefix argument, missing format specifier, etc.) are tested and verified on rustc 1.35.0 and nightly, currently. Earlier rustc versions may produce less clear errors.
