pub fn replace_nulls(value: &mut Value, placeholder: &str)Expand description
Substitutes placeholder for every null in the document.
The alternative to to_toml’s rejection, and so only ever called on the
way to TOML — JSON holds a null fine and has nothing to be rescued from. A
null cannot be encoded as TOML, leaving only two honest options: fail, or
write a value that was in none of the inputs. Which value that is has to
be the user’s choice rather than the tool’s — yq and tomlq both drop
null keys silently, and both invent a string inside arrays ("" and
"None" respectively, for the same input), which is the behaviour this
exists to avoid.
