The kernel boundary and truck
crates/kernel is SolidCraft's B-rep kernel. It wraps
truck (Apache-2.0) for topology, NURBS geometry, booleans,
tessellation and STEP parsing, and it is the only crate allowed to use truck. Callers get
SolidCraft types (Body, face and edge indices, meshes, measures) and a
KernelError instead of truck types and panics.
guard
truck can panic on geometry it doesn't handle. Every call into it goes through
solidcraft_kernel::guard, which catches the panic and turns it into
KernelError::Internal, leaving the model unchanged:
pub fn guard<T>(what: &str, f: impl FnOnce() -> Result<T>) -> Result<T>
A failing feature shows an error on the timeline; it never takes the app down.
What is our own
truck has no fillets, chamfers, shells or face edits, so these are SolidCraft code in the kernel: constant, chord and variable-radius fillets with corner blends, chamfers, shell and offset, Delete Face, Split Face, Replace Face, sewing, STEP and IGES reading and writing beyond truck's parser, and face provenance (which input face each output face came from, for persistent naming).
Vendored truck crates
Patched copies of truck-shapeops, truck-stepio and truck-meshalgo live in vendor/,
wired in with [patch.crates-io]. The patches fix robustness bugs found by our tests and the
STEP corpus. vendor/ is excluded from our fmt and clippy rules, and each patch should go
upstream when it can.
Some truck assertions only run in debug builds and can fail on valid geometry, so tests and CI
run with --release.
