type Anchor = ManuallyDrop<FileReaderSync>
The type that holds the reference to
Self
for the duration of the
invocation of the function that has an &Self
parameter. This is
required to ensure that the lifetimes don’t persist beyond one function
call, and so that they remain anonymous. Read moreAuto Trait Implementations§
