Jörg Sommer 2fc2db2848 Update dependencies 2021-05-13 17:25:48 +02:00
Jörg Sommer 4f823fba78 Use saturating arithmetic on calculating row saving 
The saturating arithmetic doesn't overflow, but stays at the maximum or
minimum. In this case it doesn't become negative, but zero, which
satisfies the condition below.

Closes #31

Jörg SommerandJan Alexander Steffens (heftig) c31ba2750f main: new argument -m to give a minimal saving 
Some compressions yield only a few hundred lines saving which isn't worth
the database update and the time needed to validate the compression. With
the new commandline argument `-m` the output would be suppressed, if not
at least the given number of database records would be saved.

Jörg SommerandJan Alexander Steffens (heftig) 88fc47d819 main: add value_name() for max_state_group 
To unify the spelling of parameters, i.e. all upper-casse, add the
`value_name()` for max_state_group.

Jörg SommerandJan Alexander Steffens (heftig) 85d185fa98 Use character for split() 
`cargo clippy` suggested to use a character instead of a string with a
single character.

See: <https://rust-lang.github.io/rust-clippy/master/index.html#single_char_pattern>

Jörg SommerandJan Alexander Steffens (heftig) 846ec8f898 Convert len() > 0 to ! is_empty() 
`cargo clippy` suggested to use `is_empty()` instead of `len() > 0`,
because this doesn't require to calculate the whole length of the sequence.

See: <https://rust-lang.github.io/rust-clippy/master/index.html#len_zero>
