Both of these modules are doc(hidden) and commented "Not public API",
but incorrect downstream code sometimes still references them. Naming
the module __private will make it more likely to be noticed in code
review.

These hit a strange error in our Emscripten builder in Travis as well as
locally through cargo web:
ERROR: failed to execute cargo: Resource temporarily unavailable (os error 11)
Also changed the generated code to have at least one thing refer to the
path directly, rather than via `use` -- This shows that the impl *can*
work without `use`, but doesn't actually do all the work to remove the
`use` lines unless we decide we need this feature to work on the 2015
edition
This is intended to be used by other crates which provide their own proc
macros and use serde internally. Today there's no consistent way to put
`#[derive(Deserialize)]` on a struct that consistently works, since
crates may be using either `features = ["derive"]` or relying on
`serde_derive` separately.
Even if we assume that everyone is using `features = ["derive"]`,
without this commit, any crate which generates
`#[derive(serde::Deserialize)]` forces its consumers to put `serde` in
their `Cargo.toml`, even if they aren't otherwise using serde for
anything.
Examples of crates which suffer from this in the real world are
tower-web and swirl.
With this feature, it's expected that these crates would have `pub
extern crate serde;` in some accessible path, and add
`#[serde(serde_path = "that_crate::wherever::serde")]` anywhere they
place serde's derives. Those crates would also have to derive
`that_crate::whatever::serde::Deserialize`, or `use` the macros
explicitly beforehand.
The test for this is a little funky, as it's testing this in a way that
is not the intended use case, or even one we want to support. It has its
own module which re-exports all of serde, but defines its own
`Serialize` and `Deserialize` traits. We then test that we generated
impls for those traits, instead of serde's. The only other way to test
this would be to create a new test crate which does not depend on serde,
but instead depends on `serde_derive` and a third crate which publicly
re-exports serde. This feels like way too much overhead for a single
test case, hence the funky test given.
I didn't see anywhere in this repo to document this attribute, so I
assume the docs will have to be done as a separate PR to a separate
repo.
Fixes#1487
Added ui test struct-representation/internally-tagged-unit
Added ui test struct-representation/internally-tagged-tuple
Limited the serde(tag = "...") to enums and structs with named field
The following changes are included:
- Delete per-file license notices at the top of each file.
- Delete the first paragraph of LICENSE-MIT (an inaccurate
pseudo-copyright line), leaving only the text of the MIT license.
Nothing about the license of Serde code has changed, only our
understanding of how to correctly communicate that license has changed.
This mirrors an equivalent change being applied in the rust-lang/rust
repository.
When originally added, this test used to contain a `#![plugin(clippy)]`.
This was removed at some point along the way, at which point this test
no longer tests anything. It prints:
warning: unknown lint: `identity_op`

which is swallowed and ignored by compiletest.
Nowadays Clippy handles warnings inside of macro expanded code
intelligently and this is something they would be responsible for
testing.
Before this change, flattening anything after a flattened map was
nonsensical because the later flattened field would always observe no
input fields.
#[derive(Deserialize)]
struct S {
#[serde(flatten)]
map: Map<K, V>,
#[serde(flatten)]
other: Other, // always empty
}
This change makes a flattened map not consume any of the input fields,
leaving them available to later flattened fields in the same struct. The
new behavior is useful when two flattened fields that both use
deserialize_map care about disjoint subsets of the fields in the input.
#[derive(Deserialize)]
struct S {
// Looks at fields with a "player1_" prefix.
#[serde(flatten, with = "prefix_player1")]
player1: Player,
// Looks at fields with a "player2_" prefix.
#[serde(flatten, with = "prefix_player2")]
player2: Player,
}
