This update for rust, rust-cbindgen fixes the following issues:
rust was updated for use by Firefox 76ESR.
Update to version 1.43.1
cargo package --list
not working with unpublished dependencies.Update to version 1.43.0
Language:
Fixed using binary operations with &{number}
(e.g. &1.0
)
not having the type inferred correctly.
#[cfg()]
can now be used on if
expressions.Syntax only changes:
type Foo: Ord
syntactically.self
in all fn
contexts.fn
syntax + cleanup item parsing.item
macro fragments can be interpolated into trait
s,
impl
s, and extern
blocks.
For example, you may now write:
macro_rules! mac_trait {
($i:item) => {
trait T { $i }
}
}
mac_trait! {
fn foo() {}
}
Compiler
You can now pass multiple lint flags to rustc to override the previous flags.
For example; rustc -D unused -A unused-variables
denies
everything in the unused
lint group except unused-variables
which is explicitly allowed. However, passing
rustc -A unused-variables -D unused
denies everything in
the unused
lint group including unused-variables
since
the allow flag is specified before the deny flag (and therefore
overridden).
