this allows you to generate rust from sample json
json_to_rust: 0.2.0
description:
pipe some json to this and it'll generate some rust for you.
usage:
cat foo.json | json_to_rust -j json_object -n MyStruct > out.rs
flags:
-u, --make-unit-tests generate unit tests
- this generates a unit test that round trips the
- serialization along with the included json sample
-m, --make-main generate a main function
- this generates a main function demoing the
- serialized and deserialized forms
-j, --json-root-name the name of the root JSON object
- this takes a string which'll be the name of
- the root json object, if applicable.
-n, --rust-root-name the name of the root Rust object
- this is the name of your root Rust struct.
- if not provided, its inferred from the json name
-t, --max-tuple heterogeneous arrays under this size will be treated as a tuple
- for types such as [1, false, "foo"] if the length exceeds the provided value
- then a Vec<Value> will be created instead. otherwise a tuple will be created.
- for the example above: a tuple of (i64, bool, String)
-d, --derive add this derive to the generate types
- this can accept a string or a comma seperated string.
- this flag can be used multiple times
- the order of the flag is the order of the derives, left to right
- it will dedup the list for you
- 'Serialize' and 'Deserialize' will be added to the end
- if this nor [-d, --derive] are provided then the full range of std derives will be used
-nd, --no-std-derives only use the serde derives
- this just uses 'Serialize' and 'Deserialize'
- if this nor [-d, --derive] are provided then the full range of std derives will be used
-f, --field-naming the casing scheme to use for fields
- this default to snake_case
- available options [snake, constant, pascal, camel]
-s, --struct-naming the casing scheme to use for structs
- this defaults to PascalCase
- available options [snake, constant, pascal, camel]
--vec-wrapper use this type for Vecs, defaults to 'Vec'
--map-wrapper use this type for Maps, defaults to 'HashMap'
--flatten-option-vec flattens Option<Vec<T>> into just Vec<T>
- this also uses serde_default which'll create an empty Vec if it was None
-v, --version show the current version
-h, --help show this message
