pub struct SourceResolver { /* private fields */ }Expand description
Per-ELF source resolver. Cheap to query (one interval-tree lookup).
Implementations§
Source§impl SourceResolver
impl SourceResolver
Sourcepub fn from_elf_path(path: &Path) -> Self
pub fn from_elf_path(path: &Path) -> Self
Builds a resolver by re-reading the ELF from disk. Returns an empty resolver when parsing fails or no text section is present.
Sourcepub fn resolve(&self, pc: u64) -> Option<SrcLoc>
pub fn resolve(&self, pc: u64) -> Option<SrcLoc>
Resolves an SBPF program counter to a (file, line) pair, or None
when DWARF is unavailable or the PC has no line entry.
Sourcepub fn resolve_frames(&self, pc: u64) -> Vec<SrcLoc>
pub fn resolve_frames(&self, pc: u64) -> Vec<SrcLoc>
Resolves an SBPF program counter to its full DWARF inlining chain, innermost-first (the deepest inlined body) out to the physical caller. Returns an empty vec when DWARF is unavailable.
resolve (via find_location) returns whichever line the DWARF
line program emitted at the PC — usually innermost, but aggressive
inlining can shove the entry back to an outer callsite. For
coverage, attributing a PC to every frame in the chain credits
the tiny #[inline(always)] wrappers (Box<T>::load,
Sysvar::load, AccountLoader::next*, etc.) that would otherwise
show 0% despite running on every transaction, matching the
behavior of llvm-cov show over expansion regions.
Sourcepub fn executable_lines(&self) -> Vec<SrcLoc>
pub fn executable_lines(&self) -> Vec<SrcLoc>
Enumerates every source line with a DWARF line-table row inside the
program’s text section. Coverage uses this to emit zero-hit LCOV DA
records for executable lines that never appeared in the trace.
