Module frames 

Extract, classify and render backtrace frames for the clean error formatter.

Shows only our-code frames: the raise line (from the captured std::panic::Location when meaningful, else the backtrace) plus our-code callers, with runs of third-party and runtime frames collapsed into a “N framework frames hidden” marker. Pure functions over FrameView so they unit-test without a real backtrace.

Structs

FrameView

A stack frame reduced to what we display and classify on.

Enums

Kind 🔒

Constants

INFRA_FILE_FRAGMENTS 🔒

Path fragments identifying error-infrastructure files.

INFRA_SYMBOL_FRAGMENTS 🔒

Symbol substrings marking a frame as error construction/conversion.

Functions

classify 🔒

clean_function

Reduce a demangled symbol to its last segment, dropping ::{{closure}} and the ::hXXXX hash suffix.

clean_path

Clean a source path to a workspace-relative form for display.

extract_frames

Extract FrameViews from a backtrace. Resolves a clone so an unresolved capture is symbolized only when formatted.

format_frame 🔒

hidden_marker 🔒

is_infra 🔒

is_infra_path

True if a path is error infrastructure, so a Location there (e.g. a From body) is not a meaningful raise site.

is_ours 🔒

render_callers 🔒

render_stack

Render one node’s raise line plus caller frames.
