Crate json_arg

CLIs (especially those designed to be called by automation) often take structured data as inputs. This ends up creating a ton of boilerplate where a CLI arg is declared as a PathBuf and then is quickly opened, read from and deserialized with some serde format crate. This crate provides two newtype wrappers (Serde and SerdeFile) that can deserialize any Serde-compatible arguments with no extra effort.

Structs

• JsonFormat
  Deserialize the argument as JSON
• Serde
  Inline JSON string. The argument provided by the caller is the raw JSON string (and the caller must consequently deal with shell quoting ahead-of-time).
• SerdeFile
  Argument that represents a serialized file. The argument provided by the caller is the path to the file that is deserialized immediately on load. The original path is preserved and accessible with SerdeFile::path
• TomlFormat
  Deserialize the argument as TOML
