[−][src]Struct slots::Key

pub struct Key<IT, N> { /* fields omitted */ }

Access key to a Slots instance

Keys must only be used with the Slots they were generated from; using them for any other access is a logic error and results in immediate or later panics from the Slot's functions. Erroneous use is largely caught by type constraints; additional runtime constraints can be enabled using the verify_owner feature.

Unless verify_owner is used, a Key is pointer-sized.

Keys can only be created by a Slot's store method.

Methods

impl<IT, N> Key<IT, N> where
    N: ArrayLength<Entry<IT>> + Unsigned, [src]

pub fn index(&self) -> usize[src]

The underlying index of the key

A key's index can be used in fallible access using the try_read() method.
