Enum SlotIndex 

pub enum SlotIndex {
    Data(usize, PartitionAccess, RwPerms),
    DataRange(Range<usize>, PartitionAccess, RwPerms),
}

SlotIndex encodes the index of a given slot and the specification of what the access rights should be for that slot. The actual enforcement is done by hardware, so if someone tries to “lie” to the API by creating a SlotIndex specifier with an inaccurate PartitionAccess spec, hardware will ignore it.

The reason the two are bundled together is that semantic priority is given to getting the spec right in the constants in this crate that define the access control tables.

Variants

Data(usize, PartitionAccess, RwPerms)

DataRange(Range<usize>, PartitionAccess, RwPerms)

Implementations

impl SlotIndex

pub fn get_access_spec(&self) -> (PartitionAccess, RwPerms)

pub fn get_type(&self) -> SlotType

pub fn get_base(&self) -> usize

pub fn len(&self) -> usize

pub fn try_into_data_offset(&self) -> Result<usize, AccessError>

Returns OutOfBounds error if the index specified in the slot is out of bounds. For ranges, returns the offset of the first element of the range.

pub fn try_into_data_iter(&self) -> Result<SlotOffsetIter, AccessError>

pub fn try_into_acl_offset(&self) -> Result<usize, AccessError>

pub fn try_into_acl_iter(&self) -> Result<SlotOffsetIter, AccessError>

Trait Implementations

impl Clone for SlotIndex

fn clone(&self) -> SlotIndex

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SlotIndex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SlotIndex

fn eq(&self, other: &SlotIndex) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
