Enum EvaluationResult 

pub enum EvaluationResult {
    DirectValue(DirectValueResult),
    MemoryLocation(LocationResult),
    Optimized,
    Composite(Vec<PieceResult>),
}

Result of evaluating a DWARF expression for eBPF code generation

Variants

DirectValue(DirectValueResult)

Direct value - expression result is the variable value (no memory read needed)

MemoryLocation(LocationResult)

Memory location - expression result is an address that needs to be dereferenced

Optimized

Variable is optimized out (no location/value available)

Composite(Vec<PieceResult>)

Composite location (multiple pieces) - for split variables

Implementations

impl EvaluationResult

pub fn as_constant(&self) -> Option<i64>

Check if this is a simple constant

pub fn merge_with_cfa(self, cfa: CfaResult, frame_offset: i64) -> Self

Merge with CFA result for frame-relative addresses (DW_OP_fbreg) This is used when a variable location is relative to the frame base

Trait Implementations

impl Clone for EvaluationResult

fn clone(&self) -> EvaluationResult

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for EvaluationResult

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for EvaluationResult

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for EvaluationResult

fn eq(&self, other: &EvaluationResult) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
