Enum ParamType 

pub enum ParamType {
    Bytes,
    Integer,
    Boolean,
    Unit,
    UtxoRef,
    Address,
    Utxo,
    AnyAsset,
    List(Box<ParamType>),
    Tuple(Vec<ParamType>),
    Map(Box<ParamType>),
    Record(Vec<(String, ParamType)>),
    Variant(Vec<VariantCase>),
    Unknown(Value),
}

Type of a transaction parameter.

This enum represents the various types that transaction parameters can have, including primitives, compound types, and references to TX3 core types. It is built from the TII params JSON schema by ParamType::from_json_schema, which never fails — any shape it does not recognize becomes ParamType::Unknown.

Variants

Bytes

Byte array type (hex-encoded).

Integer

Integer type (signed or unsigned).

Boolean

Boolean type.

Unit

Unit type ({ "type": "null" }).

UtxoRef

UTXO reference in format 0x[64hex]#[index].

Address

Bech32-encoded blockchain address.

Utxo

A resolved UTxO object.

AnyAsset

An asset identified at runtime by policy and name.

List(Box<ParamType>)

Homogeneous, variable-length sequence (array + items).

Tuple(Vec<ParamType>)

Fixed-length, positionally-typed sequence (array + prefixItems).

Map(Box<ParamType>)

String-keyed homogeneous map (object + additionalProperties).

Record(Vec<(String, ParamType)>)

User-defined record (object + properties), (field name, type) in declared order (the schema’s required array, which tx3c emits in source order — properties is alphabetized and must not drive field order). Encoding maps the user’s by-name object to positional fields.

Variant(Vec<VariantCase>)

User-defined tagged union (oneOf), externally tagged.

Unknown(Value)

A schema shape that could not be interpreted; carries the raw schema.

Implementations

impl ParamType

pub fn field(&self, name: &str) -> Option<&ParamType>

Looks up a field type by name in a ParamType::Record; None for any other kind or an absent field.

pub fn from_json_schema( schema: &Value, components: &HashMap<String, Value>, ) -> ParamType

Creates a parameter type from a JSON schema node.

Interprets every shape tx3c can emit (see the SDK spec’s api-surface/args.md). It never fails: an unrecognized shape — including a bare string, an unresolved object, or an unknown $ref — becomes ParamType::Unknown carrying the raw schema.

Arguments

• schema - The JSON schema node to interpret
• components - The TII’s components.schemas table, used to resolve #/components/schemas/<Name> references to user-defined types

Trait Implementations

impl Clone for ParamType

fn clone(&self) -> ParamType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ParamType

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

Formats the value using the given formatter.
