impl InnerSubtypeConstraint for CmsAlgorithmProtection

fn validate_and_decode_containing( self, _: Option<Codec>, ) -> Result<Self, InnerSubtypeConstraintError>

Validates the inner subtype constraints and attempts to decode internal ASN.1 CONTAINING constraints as a marked type. Usually this means that some field has OPAQUE data, and we need to decode it further as a specific type, as defined in the inner subtype constraint. Manual implementation of this function is required for all types that have inner subtype constraints.

fn validate_components(self) -> Result<Self, InnerSubtypeConstraintError>

Validates the inner subtype constraints and returns the type on success. Does not attempt to decode internal ASN.1 CONTAINING constraints as a marked type. See validate_and_decode_containing for CONTAINING validation.

impl Ord for CmsAlgorithmProtection

fn cmp(&self, other: &CmsAlgorithmProtection) -> 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 CmsAlgorithmProtection

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

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

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

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

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

fn lt(&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.
