Struct ChoiceContext 

pub struct ChoiceContext { /* private fields */ }

A choice context, ready to be used against either transport.

Implementations

impl ChoiceContext

pub fn from_wire(wire: WireChoiceContext) -> Result<Self>

Translate what the registry returned.

Errors

Error::UnexpectedResponse if a template id is not <package>:<Module>:<Entity>, or a blob is not valid base64. Both are the registry’s mistake rather than the caller’s, and both would otherwise reach the participant as something it cannot parse.

pub fn data(&self) -> &Value

The context data, as the registry sent it.

pub fn decode<T: DeserializeOwned>(&self) -> Result<T>

Decode the context data into a generated type.

The registry encodes it with the Daml JSON API’s rules, which is what canton-daml implements, so the generated ChoiceContext deserializes straight from it — no hand-written mapping.

Errors

Error::UnexpectedResponse if the data does not match T.

pub fn disclosed_contracts(&self) -> &[DisclosedContract]

The contracts to disclose, for a gRPC submission.

pub fn disclosed_contracts_json(&self) -> &[Value]

The contracts to disclose, for the JSON transport.

pub fn into_disclosed_contracts(self) -> Vec<DisclosedContract>

Take ownership of the disclosed contracts, for attaching to a submission.
