Function nom_stl::parse_stl [−][src]
pub fn parse_stl<R: Read + Seek>(bytes: &mut R) -> Result<Mesh, Error>
Parse a binary or an ASCII stl.
Binary stls ar not supposed to begin with the bytes solid
,
but unfortunately they sometimes do in the real world.
For this reason, we use a simple regex heuristic to determine
if the stl contains the bytes facet normal
, which is a byte
sequence specifically used in ASCII stls.
If the file contains this sequence, we assume ASCII, otherwise
binary. While a binary stl can in theory contain this sequence,
the odds of this are low. This is a tradeoff to avoid something
both more complicated and less performant.
