Bases: object

Represents a Move Instantaneous Reward (MIR) certificate for transferring funds to stake credentials.

This certificate is used to transfer rewards to a specified set of stake credentials from either the reserve or treasury pot.

__init__(ptr)[source]

Return type:: None

__enter__()[source]

Return type:: MirToStakeCredsCert

__exit__(exc_type, exc_val, exc_tb)[source]

Return type:: None

__repr__()[source]

Return repr(self).

Return type:: str

__len__()[source]

Returns the number of credential-to-amount mappings.

Return type:: int

__iter__()[source]

Iterates over credential-to-amount mappings.

Return type:: Iterator[Tuple[Credential, int]]

classmethod new(pot_type)[source]

Creates a new MIR to stake credentials certificate.

Parameters:: pot_type (MirCertPotType) – The accounting pot from which funds will be drawn.
Returns:: A new MirToStakeCredsCert instance.
Raises:: CardanoError – If creation fails.
Return type:: MirToStakeCredsCert

classmethod from_cbor(reader)[source]

Deserializes a MirToStakeCredsCert from CBOR data.

Parameters:: reader (CborReader) – A CborReader positioned at the certificate data.
Returns:: A new MirToStakeCredsCert deserialized from the CBOR data.
Raises:: CardanoError – If deserialization fails.
Return type:: MirToStakeCredsCert

to_cbor(writer)[source]

Serializes the certificate to CBOR format.

Parameters:: writer (CborWriter) – A CborWriter to write the serialized data to.
Raises:: CardanoError – If serialization fails.
Return type:: None

property pot: MirCertPotType

The accounting pot from which funds are drawn.

Returns:: The MirCertPotType indicating the source pot.

insert(credential, amount)[source]

Inserts a credential-to-amount mapping.

Parameters:

credential (Credential) – The stake credential to receive the reward.
amount (int) – The amount of ADA (in lovelace) to transfer.

Raises:

CardanoError – If the insertion fails.

Return type:

None

get_value_at(index)[source]

Retrieves the amount at the specified index.

Parameters:: index (int) – The index of the amount to retrieve.
Returns:: The amount in lovelace.
Raises:: CardanoError – If retrieval fails.
Return type:: int

get_key_value_at(index)[source]

Retrieves both the credential and amount at the specified index.

Parameters:: index (int) – The index of the mapping to retrieve.
Returns:: A tuple of (Credential, amount).
Raises:: CardanoError – If retrieval fails.
Return type:: Tuple[Credential, int]

to_cip116_json(writer)[source]
