I like the results - especially catching those bugs in the errors. But it seems to be a lot of overhead - a whole other crate to depend on, and three new pub definitions per thing (including a marker type that will need to be hidden from docs). If there aren't any obvious simplifications to be made I guess we can go ahead.
The new dependency is mostly for implementing all the required traits, it's a lot of boilerplate just to avoid having bounds on the Marker type. I could include that here, but it's a lot of stuff irrelevant to this crate. We could drop the |

@doug-q Requesting a second opinion here. This looks a bit boilerplate-y/confusing, but it may reduce the amount of code on the callsites.
An alternative is to drop OpNameSlice
and just use references to cloned OpName
s for parameters.

I think OpNameRef
is a better name, slicing being an uncommon operation on these types and so more distracting than helpful. One could also consider opnm
in analogy with str
, but with so many variants I think not.
I do think you want this type defined and used as args, rather than using &OpName
, although I'm having difficulty justifying it. I think it's cool, but it's hard to see this making a difference.
I think callsites should use op_name.borrow()
to obtain an &OpNameSlice
no cloning should be required.

Can you elaborate on where the cloning is necessary?

Is there a reason you omit ExtensionId
from your treatment?

I dropped the string-newtype
dependency and changed the identifier to aliases of SmolStr
.
The diff hasn't changed much aside from the identifier definitions.

I left this associated type even though it always gets instantiated with SmolStr
.
It doesn't change the way we use this trait but documents a bit better the behaviour.

Uses
string_newtype
to defineTypeName
,OpName
, andValueName
types, to avoid using stringly-typed methods everywhere.Also defines
TypeNameSlice
,OpNameSlice
,ValueNameSlice
. These that act likestr
to aString
, or lkePath
to aPathBuf
; unsized slice types used through references.OpName
trait toNamedOp
. NowNamedOp::name
returns anOpName
value.Closes #834.
As an example of why this is useful, I caught some cases where
ExtensionBuildError
was being built with the wrong variant due to mixing up the different identifiers, since everything usedSmolStr
.
