Enum FramesLookupResult 

pub enum FramesLookupResult {
    Available(Vec<FrameDebugInfo>),
    External(ExternalFileAddressRef),
}

Contains address debug info (inlined functions, file names, line numbers) if available.

Variants

Available(Vec<FrameDebugInfo>)

Debug info for this address was found in the symbol map.

This Vec contains the file name and line number of the address. If the compiler inlined a function call at this address, then this Vec also contains the function name of the inlined function, along with the file and line information inside that function.

The Vec begins with the callee-most (“innermost”) inlinee, followed by its caller, and so on. The last element is always the outer function.

External(ExternalFileAddressRef)

Debug info for this address was not found in the symbol map, but can potentially be found in a different file, with the help of SymbolMap::lookup_external.

This case can currently only be hit on macOS: On macOS, linking multiple .o files together into a library or an executable does not copy the DWARF information into the linked output. Instead, the linker stores the paths to those original .o files, using ‘OSO’ stabs entries, and debug info must be obtained from those original files.

Trait Implementations

impl Clone for FramesLookupResult

fn clone(&self) -> FramesLookupResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FramesLookupResult

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

Formats the value using the given formatter.

impl PartialEq for FramesLookupResult

fn eq(&self, other: &FramesLookupResult) -> 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.
