The transition output.

Variants

`Constant(Field<N>, Option<Plaintext<N>>)`

The plaintext hash and (optional) plaintext.

`Public(Field<N>, Option<Plaintext<N>>)`

The plaintext hash and (optional) plaintext.

`Private(Field<N>, Option<Ciphertext<N>>)`

Returns the ID of the output.

pub const fn record(&self) -> Option<(&Field<N>, &Record<N, Ciphertext<N>>)>

Returns the commitment and record, if the output is a record.

pub fn into_record(self) -> Option<(Field<N>, Record<N, Ciphertext<N>>)>

Consumes self and returns the commitment and record, if the output is a record.

pub const fn commitment(&self) -> Option<&Field<N>>

Returns the commitment, if the output is a record.

pub fn into_commitment(self) -> Option<Field<N>>

Returns the commitment, if the output is a record, and consumes self.

pub const fn nonce(&self) -> Option<&Group<N>>

Returns the nonce, if the output is a record.

pub fn into_nonce(self) -> Option<Group<N>>

Returns the nonce, if the output is a record, and consumes self.

pub const fn checksum(&self) -> Option<&Field<N>>

Returns the checksum, if the output is a record.
