Variables defined with const are hoisted to the top of the block, but not initialized. Meaning: The block of code is aware of the variable, but it cannot be used until it has been declared. The variable is in a "temporal dead zone" from the start of the block until it is declared.

It will be available in the 1.51 release, which is expected to be released on March 25th, 2021.Const generics is one of the most highly anticipated features coming to Rust, and we're excited for people to start taking advantage of the T * const would mean you can modify the T value pointed to by foo, but you cannot modify the pointer itself; so you can't say foo++; (*foo)++ because the first statement would increment (modify) the pointer. T * would give you full freedom: you get a pointer into an array, and you can inspect and modify any member of that array. const T& value() const {} This means the function value() will return a const T& type and in between (in the function) won't modify the class itself. Say I write: class Cfoo { void foo() const { //Cfoo will not be modified here } } If I directly quote from MS Docs: T const *p; declares pas a “pointer to a const T,” which is exactly what it is.

Effectively, this implies that a constant pointer is pointing to a constant value. Hence, neither the pointer should point to a new address nor the value being pointed to should be changed. Not Real Constants. The keyword const is a little misleading..

Const t&

The keyword const is a little misleading.. It does NOT define a constant value. It defines a constant reference to a value. Because of this, we cannot change constant primitive values, but we can change the properties of constant objects. The logical state of a sequence container includes the state of the elements which makes up the sequence; so in a const std::vector, the container itself (vector) as well as the elements it contains (strings) are immutable. 2020-01-03 · const int* const.

Say I write: class Cfoo { void foo() const { //Cfoo will not be modified here } } If I directly quote from MS Docs: const VP vectorTable[] One interpretation is to replace VP as follows: which makes it appear that vectorTablehas type “array of pointer to const void.” This is wrong!
