Eliminate unused variable warning when using skip_serializing inside a tuple variant of an adjacently tagged enum (#1617, thanks

@arilotter)

Support skip attribute inside of newtype variants (#1622, thanks

@Xaeroxe)

v1.0.100

Provide serde::ser::StdError and serde::de::StdError which are either a re-export of std::error::Error (if Serde's "std" feature is enabled) or a new identical trait (otherwise).

#[cfg(feature = "std")]
pub use std::error::Error as StdError;

#[cfg(not(feature = "std"))]
pub trait StdError: Debug + Display {
    fn source(&self) -> Option<&(StdError + 'static)> { None }
}

Serde's error traits serde::ser::Error and serde::de::Error require std::error::Error as a supertrait, but only when Serde is built with "std" enabled. Data formats that don't care about no_std support should generally provide their error types with a std::error::Error impl directly:

```rust
#[derive(Debug)]
struct MySerError {...}

impl serde::ser::Error for MySerError {...}

impl std::fmt::Display for MySerError {...}

// We don't support no_std!
impl std::error::Error for MySerError {}
```

Data formats that do support no_std may either have a "std" feature of their own as has been required in the past:

```toml
[features]
std = ["serde/std"]
```

```rust
#[cfg(feature = "std")]
impl std::error::Error for MySerError {}
```

... or else now may provide the std Error impl unconditionally via Serde's re-export:

```rust
impl serde::ser::StdError for MySerError {}
```

v1.0.99

Update Syn dependency to 1.0.

Note: This raises the minimum required compiler version for serde_derive from rustc 1.15 to rustc 1.31. The minimum required compiler version for serde remains at rustc 1.13.

@Flaise)

v1.0.97

Introduce serde(try_from = "...") attribute to derive Deserialize based on a given implementation of std::convert::TryFrom (#1526, thanks

@fanzeyi)

enum N {
    Zero,
    One,
    Two,
}

impl TryFrom<u32> for N {
    type Error = String;

    fn try_from(u: u32) -> Result<Self, Self::Error> {
        match u {
            0 => Ok(Self::Zero),
            1 => Ok(Self::One),
            2 => Ok(Self::Two),

Support deserializing from MapAccessDeserializer into an enum (#1522)

v1.0.90

Add an attribute #[serde(crate = "path::to::serde")] which replaces the use of extern crate serde in the generated code; this is intended for crates that invoke Serde derives from a macro and need to refer to serde through their own re-export rather than requiring callers to list Serde in Cargo.toml (#1499, thanks

@sgrif)

```rust
#[derive(Deserialize)]
#[serde(crate = "__tw::codegen::serde")]
struct S { ... }

Accept #[serde(alias = "...")] attribute on fields and variants which allows the same field or variant to be deserialized from any of multiple different names in the input (#1458, thanks

@Lymia)

```rust

    #[serde(alias = "old_name")]

new_name: String, // will deserialize from either of "old_name" or "new_name" } ```

v1.0.84

    deserialize = "SCREAMING_SNAKE_CASE",

```

Performance optimization for Vec::deserialize_in_place to deserialize elements in place (#1411)

v1.0.79

Add serde(other) variant attribute for deserializing any variant that is not one of the others (#1382)

#[derive(Deserialize)]
#[serde(tag = "variant")]
enum MyEnum {
    A(ModelA),
    B(ModelB),
    #[serde(other)]
    Unknown,
}

In this internally tagged enum the MyEnum::Unknown variant would be produced if the "variant" tag in the input is neither "A" nor "B".

This feature is currently limited to externally tagged and adjacently tagged enums in which the other variant is a unit variant.
