Implementations§

source§

impl<N: Network> Input<N>

source

pub const fn variant(&self) -> u8

Returns the variant of the input.

source

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

Returns the ID of the input.

source

pub fn to_transition_leaf(&self, index: u8) -> TransitionLeaf<N>

Returns the input as a transition leaf.

source

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

Returns the tag, if the input is a record.

source

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

Returns the tag, if the input is a record, and consumes self.

source

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

Returns the serial number, if the input is a record.

source

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

Returns the serial number, if the input is a record, and consumes self.

source

pub fn verifier_inputs(&self) -> impl '_ + Iterator<Item = N::Field>
