Enum rustc_mir::borrow_check::ReadOrWrite[−][src]

enum ReadOrWrite {
    Read(ReadKind),
    Write(WriteKind),
    Reservation(WriteKind),
    Activation(WriteKind, BorrowIndex),
}
Expand description

Kind of access to a value: read or write (For informational purposes only)

Variants

Read(ReadKind)
Expand description

From the RFC: “A read means that the existing data may be read, but will not be changed.”

Write(WriteKind)
Expand description

From the RFC: “A write means that the data may be mutated to new values or otherwise invalidated (for example, it could be de-initialized, as in a move operation).

Reservation(WriteKind)
Expand description

For two-phase borrows, we distinguish a reservation (which is treated like a Read) from an activation (which is treated like a write), and each of those is furthermore distinguished from Reads/Writes above.

Activation(WriteKind, BorrowIndex)
