alexcrichton opened PR #3241 from traps-binary to main:

This commit moves the traps field of FunctionInfo into a section of
the compiled artifact produced by Cranelift. This section is quite large
and when previously encoded/decoded with bincode this can take quite
some time to process. Traps are expected to be relatively rare and it's
not necessarily the right tradeoff to spend so much time
serializing/deserializing this data, so this commit offloads the section
into a custom-encoded binary format located elsewhere in the compiled image.

This is similar to #3240 in its goal which is to move very large pieces
of metadata to their own sections to avoid decoding anything when we
load a precompiled modules. This also has a small benefit that it's
slightly more efficient storage for the trap information too, but that's
a negligible benefit.

This is part of #3230 to make loading modules fast.

Nit: rename this function and one changed below to lookup_trap_code?
