Cache

playdate_fs::api

Struct Cache 

Source 
pub struct Cache(/* private fields */);
Expand description

Cached file system api end-point.

Useful if you’re making many operations on fs.

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.
