ClassicalRemap

cqlib_core::compile::transform::rebuild

Struct ClassicalRemap 

Source 
pub struct ClassicalRemap { /* private fields */ }
Expand description

Mapping from source-circuit runtime classical handles to rebuilt handles.

Values of this type are produced by CircuitRebuildContext. The mapping internals are intentionally private so callers cannot create partial remaps that violate the rebuilt circuit’s classical ownership invariants.

§Standalone use

A ClassicalRemap is self-contained once obtained from CircuitRebuildContext::root_classical or CircuitRebuildContext::allocate_classical_instance. All remap methods on this type work without holding a reference to the rebuild context, so callers can pass the remap into helper functions freely.

Implementations§

Source§

impl ClassicalRemap

Source

pub fn map_var(&self, var: ClassicalVar) -> Option<ClassicalVar>

Returns the rebuilt handle for var, if this remap covers it.

Source

pub fn map_value(&self, value: ClassicalValue) -> Option<ClassicalValue>

Returns the rebuilt handle for value, if this remap covers it.

Source

pub fn remap_var( &self, var: ClassicalVar, ) -> Result<ClassicalVar, CompilerError>

Remaps a classical variable, failing if this remap does not cover it.

Source

pub fn remap_value( &self, value: ClassicalValue, ) -> Result<ClassicalValue, CompilerError>

Remaps a classical value, failing if this remap does not cover it.

Source

pub fn remap_expr( &self, expr: &ClassicalExpr, ) -> Result<ClassicalExpr, CompilerError>

Remaps runtime classical variable and value reads inside an expression.

Every ClassicalVar and ClassicalValue read by expr must be covered by this remap, otherwise an error is returned.

Source

pub fn remap_data_op( &self, op: &ClassicalDataOp, ) -> Result<ClassicalDataOp, CompilerError>

Remaps classical handles inside a runtime classical data operation.

Covers ClassicalDataOp::Store (target variable and value expression), ClassicalDataOp::MeasureBit, and ClassicalDataOp::MeasureBits (result value).
