piccolog

A very minimal Log output implementation for testing of body-image*, barc* and related crates, and for use with barc-cli. Output is directed to STDERR. When logging with tests, a TEST_LOG environment variable is read to configure a course-grained logging level:

TEST_LOG=0 : The default, no logging enabled.

TEST_LOG=1 : The Info log level.

TEST_LOG=2 : The Debug log level, but dependencies are filtered to Info log level.

TEST_LOG=3 : The Debug log level (for all).

TEST_LOG=4 (or higher) : The Trace log level (for all).

Minimum supported rust version

MSRV := 1.39.0

The crate will fail fast on any lower rustc (via a build.rs version check) and is also CI tested on this version.
