David Tolnay 8909fc0c60 Enforce derive cannot be used against serde_core
Even for a simple data structure that would ordinarily expand to an impl
that only refers to the public Serde traits without serde::__private, we
still disallow a (renamed) serde_core dependency. This leaves the
liberty to new usage of private helpers in such impls over time. For
example, similar to the optimization of the standard library's
derive(Debug) that introduced debug_struct_field1_finish to improve
compile time of derived impls.

David Tolnay 3c747e4585 Relocate serde_derive version constraint from serde to serde_core
This disallows using an old version of serde_derive against a new
version of serde_core (with a rename to serde in Cargo.toml).

David Tolnay c069b5c640 Forcibly enable serde_core/result when using serde
Making Result impls get disabled when using `serde = { version = "1",
default-features = false }` would have been a breaking change.

Override diagnostic::on_unimplemented message for all serde_core traits
2025-09-13 14:07:43 -07:00
David Tolnay 4bddf1b953 Override diagnostic::on_unimplemented message of all serde_core traits
This prevents diagnostics being rendered like `serde_core::ser::Serialize`
and `serde_core::de::Deserialize` in projects that have no direct
dependency on serde_core.

The attributes make error messages arguably sometimes worse than
pre-serde_core by always rendering `serde::Serialize` and never
`Serialize` when `use serde::Serialize` is in scope, which rustc's
default message construction knows to recognize. But this is probably
negligible.

I explored the alternative of setting `[lib] name = "serde"` in
serde_core/Cargo.toml which also prevents `serde_core::ser::Serialize`
in messages, but has the unwanted effect of also inserting the following
noise into every such error:

    note: there are multiple different versions of crate `serde` in the dependency graph
