Expand description

An error that can occur when JitterRng::test_timer fails.

Variants

`NoTimer`

No timer available.

`CoarseTimer`

Timer too coarse to use as an entropy source.

`NotMonotonic`

Timer is not monotonically increasing.

`TinyVariantions`

Variations of deltas of time too small.

`TooManyStuck`

Too many stuck results (indicating no added entropy).
