use generic_array::typenum::U5;struct Foo<T,N:ArrayLength<T>>{data:GenericArray<T,N>}fnmain(){letfoo=Foo::<i32,U5>{data:GenericArray::default()};} 如此一来我们就可以绕开Rust本身的限制,对静态数组的长度使用范型,让它动起来～不过其实Rust 2021发行版本据说就要原生支持这一功能了,大家也可以...

Output: Generic Array <Integer>: [2, 4, 6, 8, 10]Generic Array <String>: [a, b, c, d, e] Use the Reflection Class to Create Generic Arrays in Java In this type of approach, a reflection class is used to create a generic array whose type will be known at the runtime only. ...

Before Rust 1.51, arrays [T; N] were problematic in that they couldn't be generic with respect to the length N, so this wouldn't work: struct Foo<N> { data: [i32; N], } Since 1.51, the below syntax is valid: struct Foo<const N: usize> { data: [i32; N], } However, the...
rust-lang/unsafe-code-guidelines#73 The TL;DR: is that, if have an union U { a: WithNiche, b: NoNiche }, where both types have the same size such that they fully overlap, then U cannot have a niche. However, if you have an union V { a: (), b: WithNiche }, then ...

We just bumped all of the RustCrypto crates to generic-array v0.14, which adds some nice features: RustCrypto/traits#95 It'd be great if heapless got updated too so we could share a single version of generic-array (which hasn't happened so far as the RustCrypto crates were previously ...
