Cache

playdate_menu::api

Struct Cache

pub struct Cache(/* private fields */);

Expand description

Cached system menu api end-point.

Stores one reference, so size on stack is eq usize.

All calls approximately costs ~1 deref.

Layout§

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
