Crate atelier_json 

Reads and writes the JSON AST representation described in the specification.

As that there is no separate model-level namespace, all shape names have been made absolute in this representation. This is a problem when constructing the model, if there are shapes from different namespaces present the parser will return an error at this time.

Example

The following JSON demonstrates the structure of the AST format.

{
    "smithy": "1.0",
    "metadata": {
        "authors": [
            "Simon"
        ]
    },
    "shapes": {
        "smithy.example#MyString": {
            "type": "string",
            "traits": {
                "smithy.api#documentation": "My documentation string",
                "smithy.api#tags": [
                    "a",
                    "b"
                ]
            }
        },
        "smithy.example#MyList": {
            "type": "list",
            "member": {
                "target": "smithy.api#String"
            }
        },
        "smithy.example#MyStructure": {
            "type": "structure",
            "members": {
                "stringMember": {
                    "target": "smithy.api#String",
                    "traits": {
                        "smithy.api#required": {}
                    }
                },
                "numberMember": {
                    "target": "smithy.api#Integer"
                }
            }
        }
    }
}

The following will parse the model above.

use atelier_core::io::read_model_from_string;
use atelier_json::JsonReader;

let mut reader = JsonReader::default();
let result = read_model_from_string(&mut reader, JSON);
if result.is_err() {
    println!("{:?}", result);
}
assert!(result.is_ok());
println!("{:#?}", result.unwrap());

Structs

JsonReader

This struct implements the ModelReader trait to read a Model from the JSON AST representation.

JsonWriter

This struct implements the ModelWriter trait to write a Model in the JSON AST representation.

Constants

FILE_EXTENSION

The extension to use when reading from, or writing to, files of this type.

REPRESENTATION_NAME

The name to report in errors in this representation.

Functions

model_to_json

Return a JSON AST representation of a model. The return value is a [Serde JSON/(https://docs.serde.rs/serde_json/) Value that represents the top-level model.
