Struct EccBackendOperation 

pub struct EccBackendOperation<'op, O: EccOperation> { /* private fields */ }

An ECC operation that can be enqueued on the work queue.

Implementations

impl<'op, O: EccOperation> EccBackendOperation<'op, O>

pub fn with_scalar_result( self, out: &'op mut [u8], ) -> Result<Self, OperationError>

where O: OperationReturnsScalar,

Designate a buffer for the scalar result of the operation.

Once the operation is processed, the result can be retrieved from the designated buffer.

Errors

OperationError::ParameterLengthMismatch when out is not the correct size.

pub fn with_affine_point_result( self, px: &'op mut [u8], py: &'op mut [u8], ) -> Result<Self, OperationError>

where O: OperationReturnsAffinePoint,

Designate buffers for the affine point result of the operation.

Once the operation is processed, the result can be retrieved from the designated buffers.

Errors

OperationError::ParameterLengthMismatch when x or y are not the correct size.

pub fn with_jacobian_point_result( self, qx: &'op mut [u8], qy: &'op mut [u8], qz: &'op mut [u8], ) -> Result<Self, OperationError>

where O: OperationReturnsJacobianPoint,

Designate buffers for the Jacobian point result of the operation.

Once the operation is processed, the result can be retrieved from the designated buffers.

Errors

OperationError::ParameterLengthMismatch when x, y, or z are not the correct size.

pub fn point_on_curve(&self) -> bool

where O: OperationVerifiesPoint,

Returns whether the input point is on the curve.

The operation must be processed before this method returns a meaningful value.

pub fn process(&mut self) -> EccHandle<'_>

Starts processing the operation.

The returned EccHandle must be polled to completion before the operation is considered complete.
