MemoryRegionArray

ostd::boot::memory_region

Struct MemoryRegionArray 

Source 
pub struct MemoryRegionArray<const LEN: usize = MAX_REGIONS> { /* private fields */ }
Expand description

A heapless set of memory regions.

The set cannot contain more than LEN regions.

Implementations§

Source§

impl<const LEN: usize> MemoryRegionArray<LEN>

Source

pub const exec fn new() -> ret : Self

ensures
ret.inv(),
ret@ == MemoryRegionArrayModel::<LEN>::new(),

Constructs an empty set.

Source

pub const exec fn VERUS_UNERASED_PROXY__new() -> ret : Self

ensures
ret.inv(),
ret@ == MemoryRegionArrayModel::<LEN>::new(),

Constructs an empty set.

Source

pub exec fn push(&mut self, region: MemoryRegion) -> ret : Result<(), &'static str>

requires
old(self).inv(),
region.inv(),
!old(self)@.full(),
ensures
self.inv(),
self@ == old(self)@.push(region@),
ret.is_ok(),

Appends a region to the set.

If the set is full, an error is returned.
