Implementations§

Source§

impl VariableReadPlan

Source

pub fn from_visible_variable( variable: VisibleVariable, provenance: Provenance, ) -> Self

Source

pub fn bpf_lowering_plan( &self, capabilities: &RuntimeCapabilities, ) -> VariableLoweringPlan

Source

pub fn materialization_plan( &self, capabilities: &RuntimeCapabilities, ) -> VariableMaterializationPlan

Source

pub fn lvalue_address_plan(&self) -> LvalueAddressPlan

Source

pub fn plan_access_path(&self, path: &VariableAccessPath) -> Result<Self>

Source

pub fn plan_pointer_element_index(&self, index: i64) -> Result<Self>

Plan pointer-style element access for expressions like ptr +/- K.

This keeps pointer dereference and element-size scaling in the DWARF semantic layer instead of making compiler lowering rewrite locations.
