Implementations
sourceimpl<C: CurveAffine, EccChip: EccInstructions<C>> NonIdentityPoint<C, EccChip>
impl<C: CurveAffine, EccChip: EccInstructions<C>> NonIdentityPoint<C, EccChip>
sourcepub fn new(
chip: EccChip,
layouter: impl Layouter<C::Base>,
value: Option<C>
) -> Result<Self, Error>
pub fn new(
chip: EccChip,
layouter: impl Layouter<C::Base>,
value: Option<C>
) -> Result<Self, Error>
Constructs a new point with the given value.
sourcepub fn constrain_equal<Other: Into<Point<C, EccChip>> + Clone>(
&self,
layouter: impl Layouter<C::Base>,
other: &Other
) -> Result<(), Error>
pub fn constrain_equal<Other: Into<Point<C, EccChip>> + Clone>(
&self,
layouter: impl Layouter<C::Base>,
other: &Other
) -> Result<(), Error>
Constrains this point to be equal in value to another point.
sourcepub fn inner(&self) -> &EccChip::NonIdentityPoint
pub fn inner(&self) -> &EccChip::NonIdentityPoint
Returns the inner point.
sourcepub fn from_inner(chip: EccChip, inner: EccChip::NonIdentityPoint) -> Self
pub fn from_inner(chip: EccChip, inner: EccChip::NonIdentityPoint) -> Self
Wraps the given point (obtained directly from an instruction) in a gadget.
sourcepub fn add<Other: Into<Point<C, EccChip>> + Clone>(
&self,
layouter: impl Layouter<C::Base>,
other: &Other
) -> Result<Point<C, EccChip>, Error>
pub fn add<Other: Into<Point<C, EccChip>> + Clone>(
&self,
layouter: impl Layouter<C::Base>,
other: &Other
) -> Result<Point<C, EccChip>, Error>
Returns self + other
using complete addition.
sourcepub fn add_incomplete(
&self,
layouter: impl Layouter<C::Base>,
other: &Self
) -> Result<Self, Error>
pub fn add_incomplete(
&self,
layouter: impl Layouter<C::Base>,
other: &Self
) -> Result<Self, Error>
Returns self + other
using incomplete addition.
The arguments are type-constrained not to be the identity point,
and since exceptional cases return an Error, the result also cannot
be the identity point.
