Function wasmtime_environ::lookup_file_pos
source · [−]Expand description
Lookup an offset within an encoded address map section, returning the
original FilePos that corresponds to the offset, if found.
This function takes a section as its first argument which must have been
created with AddressMapSection above. This is intended to be the raw
ELF_WASMTIME_ADDRMAP section from the compilation artifact.
The offset provided is a relative offset from the start of the text
section of the pc that is being looked up. If offset is out of range or
doesn’t correspond to anything in this file then None is returned.
