Enum CardanoNodePlutusDatumSchema 

pub enum CardanoNodePlutusDatumSchema {
    BasicConversions,
    DetailedSchema,
}

JSON <-> PlutusData conversion schemas. Follows ScriptDataJsonSchema in cardano-cli defined at: https://github.com/input-output-hk/cardano-node/blob/master/cardano-api/src/Cardano/Api/ScriptData.hs#L254

All methods here have the following restrictions due to limitations on dependencies:

• JSON numbers above u64::MAX (positive) or below i64::MIN (negative) will throw errors
• Hex strings for bytes don’t accept odd-length (half-byte) strings. cardano-cli seems to support these however but it seems to be different than just 0-padding on either side when tested so proceed with caution

Variants

BasicConversions

ScriptDataJsonNoSchema in cardano-node.

This is the format used by –script-data-value in cardano-cli This tries to accept most JSON but does not support the full spectrum of Plutus datums. From JSON:

• null/true/false/floats NOT supported
• strings starting with 0x are treated as hex bytes. All other strings are encoded as their utf8 bytes. To JSON:
• ConstrPlutusData not supported in ANY FORM (neither keys nor values)
• Lists not supported in keys
• Maps not supported in keys

DetailedSchema

ScriptDataJsonDetailedSchema in cardano-node.

This is the format used by –script-data-file in cardano-cli This covers almost all (only minor exceptions) Plutus datums, but the JSON must conform to a strict schema. The schema specifies that ALL keys and ALL values must be contained in a JSON map with 2 cases:

1. For ConstrPlutusData there must be two fields “constructor” contianing a number and “fields” containing its fields e.g. { “constructor”: 2, “fields”: [{“int”: 2}, {“list”: [{“bytes”: “CAFEF00D”}]}]}
2. For all other cases there must be only one field named “int”, “bytes”, “list” or “map” BigInteger’s value is a JSON number e.g. {“int”: 100} Bytes’ value is a hex string representing the bytes WITHOUT any prefix e.g. {“bytes”: “CAFEF00D”} Lists’ value is a JSON list of its elements encoded via the same schema e.g. {“list”: [{“bytes”: “CAFEF00D”}]} Maps’ value is a JSON list of objects, one for each key-value pair in the map, with keys “k” and “v” respectively with their values being the plutus datum encoded via this same schema e.g. {“map”: [ {“k”: {“int”: 2}, “v”: {“int”: 5}}, {“k”: {“map”: [{“k”: {“list”: [{“int”: 1}]}, “v”: {“bytes”: “FF03”}}]}, “v”: {“list”: []}} ]} From JSON:

• null/true/false/floats NOT supported
• the JSON must conform to a very specific schema To JSON:
• all Plutus datums should be fully supported outside of the integer range limitations outlined above.

Trait Implementations

impl Clone for CardanoNodePlutusDatumSchema

fn clone(&self) -> CardanoNodePlutusDatumSchema

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CardanoNodePlutusDatumSchema

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<CardanoNodePlutusDatumSchema> for JsValue

fn from(value: CardanoNodePlutusDatumSchema) -> JsValue

Converts to this type from the input type.

impl FromWasmAbi for CardanoNodePlutusDatumSchema

type Abi = u32

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> CardanoNodePlutusDatumSchema

Recover a Self from Self::Abi.

impl IntoWasmAbi for CardanoNodePlutusDatumSchema

type Abi = u32

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl OptionFromWasmAbi for CardanoNodePlutusDatumSchema

fn is_none(val: &<CardanoNodePlutusDatumSchema as FromWasmAbi>::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for CardanoNodePlutusDatumSchema

fn none() -> <CardanoNodePlutusDatumSchema as IntoWasmAbi>::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl PartialEq for CardanoNodePlutusDatumSchema

fn eq(&self, other: &CardanoNodePlutusDatumSchema) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TryFromJsValue for CardanoNodePlutusDatumSchema

type Error = JsValue

The type returned in the event of a conversion error.

fn try_from_js_value( value: JsValue, ) -> Result<CardanoNodePlutusDatumSchema, <CardanoNodePlutusDatumSchema as TryFromJsValue>::Error>

Performs the conversion.

impl VectorFromWasmAbi for CardanoNodePlutusDatumSchema

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi( js: <CardanoNodePlutusDatumSchema as VectorFromWasmAbi>::Abi, ) -> Box<[CardanoNodePlutusDatumSchema]>

impl VectorIntoWasmAbi for CardanoNodePlutusDatumSchema

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi

fn vector_into_abi( vector: Box<[CardanoNodePlutusDatumSchema]>, ) -> <CardanoNodePlutusDatumSchema as VectorIntoWasmAbi>::Abi
