build(deps): bump the all-deps group across 1 directory with 5 updates

[dependabot]

Bumps the all-deps group with 2 updates in the / directory: libc and serde.

Updates libc from 0.2.186 to 0.2.189

Release notes

Sourced from libc's releases.

0.2.189

Added

• Emscripten: Add pthread_sigmask, sigwait, sigwaitinfo, sigtimedwait, faccessat, and pthread_kill (#5270)
• Linux SPARC: Enable the clone3 syscall (#4980)
• Solarish: Add CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID (#5274)

Deprecated

• Deprecate CLONE_INTO_CGROUP and CLONE_CLEAR_SIGHAND. These overflow their types and will be changed to a larger size in the future. (8c6e6710458d)

Fixed

• Musl riscv32: Rename padding fields to avoid a conflict and fix the build (2499ff0ad993)
• NuttX: Fix wchar_t definition under Arm (#5245)
• Windows: Add back link names for time-related symbols (#5300)

0.2.188

Changed

• Restore Send and Sync for DIR (35b062263401)

These were removed in 0.2.187 because libc does not actually make Send and Sync guarantees about DIR (or other extern types), but this caused some crates to break. The traits are added back for now to allow time to migrate, but will be removed again in the future; please make sure your crates are not relying on libc::DIR: Send or libc::DIR: Sync.

0.2.187

This release contains a number of improvements related to 64-bit time_t configuration. Of note the existing RUST_LIBC_UNSTABLE_* environment variables have been replaced with configuration options. The new way to use these is:

RUSTFLAGS='--cfg=libc_unstable_musl_v1_2_3' cargo ...
RUSTFLAGS='--cfg=libc_unstable_gnu_time_bits="64"' cargo ...

Being able to set this via RUSTFLAGS makes it easier to only apply configuration to specific targets (and notably, not the host if build scripts are used).

There are two other notable changes:

• The 32-bit windows-gnu targets now respect libc_unstable_gnu_time_bits

• uClibc now supports a similar configuration option:

  RUSTFLAGS='--cfg=libc_unstable_uclibc_time64'

... (truncated)

Updates syn from 2.0.118 to 3.0.3

Release notes

Sourced from syn's releases.

3.0.3

• Documentation improvements

3.0.2

• Add Error::new_range(start..end, "msg") (#2068, #2070)
• Add Cursor::prev_span

3.0.1

• Parse const traits (#2056, #2057, #2058, #2063, #2064)
• Parse unsafe binder types (#2065)
• Parse impl restrictions (#2066)

3.0.0

This release contains adjustments to the syntax tree to account for ongoing Rust language development from the 3 years since syn 2.0.0 and to anticipate some in-flight Rust language RFCs.

These include: default values in fields, pinned type sugar, raw lifetimes, generator blocks and functions, unnamed enum variants, attributes in tuple types and tuple patterns, named arguments in parenthesized generic argument lists, lightweight clones, const traits, const function pointers, mutability restricted fields, supertrait auto implementation, final associated functions, trait implementability restrictions, const blocks in path arguments, item-level const blocks, return type notation, never patterns, function delegation, mutable by-reference bindings, in-place initialization, field projections, explicitly dyn-compatible traits, view types, file-level frontmatter, generic const arguments, guard patterns, lazy type aliases, explicitly safe foreign items, super let, unsafe fields, pattern types, heterogeneous try-blocks, function contracts, async function trait bounds, static closure coroutine syntax, unsafe binder types, move expressions, for-await loops, and postfix keywords.

Breaking changes

Modifiers

To reserve more room for language evolution, there are 10 new non-exhaustive structs in the syntax tree having the following commonality:

• Name ending in Modifiers. {BlockModifiers, ClosureModifiers, ConstModifiers, FieldModifiers, FnModifiers, ImplModifiers, LocalModifiers, TraitBoundModifiers, TraitModifiers, TypeModifiers}

• Each implements Default. The default value is guaranteed to comprise no tokens.

• Non-exhaustive. Can only be instantiated by Syn's parser or by creating and then mutating ▁▁Modifiers::default().

• Does not implement Parse. When parsing, they are parsed by the enclosing syntax tree node.

• Does not implement ToTokens. In some cases the syntax that these nodes might hold in the future is not necessarily contiguous tokens.

• Provides .require_empty() -> Result<()> which returns a meaningfully spanned error if the modifiers are different from the empty default. This enables a caller to reject syntax it does not recognize without knowing what that syntax may be.

Types

• Type::BareFn has been renamed to Type::FnPtr to mirror the compiler's terminology. Together with this, BareVariadic is renamed to FnPtrVariadic.

• The mutually exclusive const_token and mutability fields of Type::Ptr have been unified into an enum of type PointerMutability, which was already previously used by Expr::RawAddr.

• Every Type variant now holds attributes, which can represent the attributes of element types inside a tuple type, or attributes for a function return type.

• BareFnArg is renamed to NamedArg and is used in ParenthesizedGenericArguments, in addition to the existing use in Type::FnPtr.
