The utility library of the project contains utility functionality which is
|
|
|
|
|
used by all other libraries and/or binaries.
|
|
|
|
|
|
|
|
|
|
It is explicitely not intended for module-use only, but for all other libraries.

This helper implements functionality to split key-value string into two parts.
|
|
|
|
|
It was introduced to simplify commandline specification for header fields (see
|
|
|
|
|
@lst:kvsplit:headerspec).
|
|
|
|
|
|
|
|
|
|
```{#lst:kvsplit:headerspec .bash .numberLines caption="Headerfield spec"}
|
|
|
|
|
imag store create --path /some.entry entry --header field=foo
|
|
|
|
|
# ^^^^^^^^^
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
It is implemented by introducing a `KeyValue` type which is generic over Key
|
|
|
|
|
and Value. This type gets implemented `KeyValue<String, String> for String` to
|
|
|
|
|
be able to split a `String` into two `String` objects, key and value
|
|
|
|
|
respectively. The implementation is realized via Regex.
|
|
|
|
|
|
|
|
|
|
The `KeyValue` type implementes `Into<(K, V)>` for convenience.
