Struct AlgorithmPolicy 

pub struct AlgorithmPolicy<'a> { /* private fields */ }

Closed algorithm admission policy for a verification context.

Implementations

impl<'a> AlgorithmPolicy<'a>

pub const fn new( admitted: &'a [SignatureAlgorithm], ) -> Result<Self, VerificationError>

Creates an algorithm admission policy from an explicit allow-list.

Admitting several algorithms lets the sender choose any admitted algorithm, including the weakest one. High-assurance deployments should admit exactly one algorithm for an operation class unless downgrade behavior is explicitly part of the profile security contract.

pub const fn deny_all() -> Self

Creates an explicit deny-all algorithm policy.

pub const fn admits(&self, algorithm: SignatureAlgorithm) -> bool

Returns true when the algorithm is admitted by this policy.

Trait Implementations

impl<'a> Clone for AlgorithmPolicy<'a>

fn clone(&self) -> AlgorithmPolicy<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Copy for AlgorithmPolicy<'a>

impl<'a> Debug for AlgorithmPolicy<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for AlgorithmPolicy<'a>

impl<'a> PartialEq for AlgorithmPolicy<'a>

fn eq(&self, other: &AlgorithmPolicy<'a>) -> 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.
