Struct MlsLevel 

pub struct MlsLevel { /* private fields */ }

Security level in MLS (Multi-Level Security), consisting of a sensitivity and a set of categories.

Implementations

impl MlsLevel

pub fn category_spans(&self) -> impl Iterator<Item = IdSpan<CategoryId>> + '_

pub fn to_string(&self, parsed_policy: &ParsedPolicy) -> Vec<u8>

impl MlsLevel

pub fn new(sensitivity: SensitivityId, categories: IdSet<CategoryId>) -> Self

Constructs a new MlsLevel.

pub fn sensitivity(&self) -> SensitivityId

Returns the sensitivity level.

pub fn categories(&self) -> &IdSet<CategoryId>

Returns the set of categories.

pub fn category_ids(&self) -> impl Iterator<Item = CategoryId> + use<'_>

Returns an iterator over the category IDs.

pub fn compare(&self, other: &Self) -> Option<Ordering>

Compares two MlsLevels. Returns None if they are incomparable.

pub fn dominates(&self, other: &Self) -> bool

Returns true if self dominates other (i.e. is greater than or equal to).

Trait Implementations

impl Clone for MlsLevel

fn clone(&self) -> MlsLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MlsLevel

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

Formats the value using the given formatter.

impl Parse for MlsLevel

type Error = Error

The type of error that may be returned from parse(), usually [ParseError] or anyhow::Error.

fn parse<'a>( cursor: PolicyCursor<'a>, ) -> Result<(Self, PolicyCursor<'a>), Self::Error>

Parses a Self from bytes, returning the Self and trailing bytes, or an error if bytes corresponding to a Self are malformed.

impl PartialEq for MlsLevel

fn eq(&self, other: &MlsLevel) -> 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.
