Struct ActorCapabilities 

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

Capabilities for an actor certificate.

This newtype wraps Capabilities and guarantees that the contained capabilities satisfy all actor-specific constraints (non-CA, signing capability present). Use ActorCapabilities::try_new to construct one from arbitrary Capabilities, or ActorCapabilities::default for the standard actor defaults.

Implementations

impl ActorCapabilities

pub fn try_new(key_usages: KeyUsages) -> Result<Self, ConstraintError>

Creates actor capabilities from key usages.

CA flag is always false for actors, and path_length is always None.

Errors

Returns a crate::errors::ConstraintError if the capabilities are not valid for an actor (e.g. signing capability missing).

Methods from Deref<Target = Capabilities>

pub fn validate(&self) -> Result<(), ConstraintError>

Validates that these capabilities are well-formed according to X.509 and polyproto constraints. This validation is target-independent.

Errors

Returns a crate::errors::ConstraintError if the capabilities are malformed.

pub fn validate_for_actor(&self) -> Result<(), ConstraintError>

Validates that these capabilities are correct for an actor certificate.

In addition to the base validation, this checks:

• The CA flag must be false
• Must have DigitalSignature or ContentCommitment
• Must not have KeyCertSign

Errors

Returns a crate::errors::ConstraintError if the capabilities are not valid for an actor.

pub fn validate_for_home_server(&self) -> Result<(), ConstraintError>

Validates that these capabilities are correct for a home server certificate.

In addition to the base validation, this checks:

• The CA flag must be true
• Must have KeyCertSign

Errors

Returns a crate::errors::ConstraintError if the capabilities are not valid for a home server.

Trait Implementations

impl Clone for ActorCapabilities

fn clone(&self) -> ActorCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ActorCapabilities

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

Formats the value using the given formatter.

impl Default for ActorCapabilities

fn default() -> Self

Returns the “default value” for a type.

impl Deref for ActorCapabilities

type Target = Capabilities

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Eq for ActorCapabilities

impl From<ActorCapabilities> for Capabilities

fn from(value: ActorCapabilities) -> Self

Converts to this type from the input type.

impl Hash for ActorCapabilities

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ActorCapabilities

fn cmp(&self, other: &ActorCapabilities) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for ActorCapabilities

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

impl PartialOrd for ActorCapabilities

fn partial_cmp(&self, other: &ActorCapabilities) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StructuralPartialEq for ActorCapabilities

impl TryFrom<Capabilities> for ActorCapabilities

type Error = ConstraintError

The type returned in the event of a conversion error.

fn try_from(value: Capabilities) -> Result<Self, Self::Error>

Performs the conversion.
