Struct KeyCandidateBudget 

pub struct KeyCandidateBudget { /* private fields */ }

Aggregate key-candidate work allowance for one cryptographic operation.

Resolver implementations must consume one unit before each key lookup or unwrap attempt. A single budget is shared across direct and recipient keys.

Implementations

impl KeyCandidateBudget

pub fn for_operation() -> Self

Create the fixed implementation-wide budget for one operation.

pub fn with_limit(maximum: usize) -> Self

Create a budget from a validated operation policy ceiling.

pub const fn remaining(&self) -> usize

Number of candidate attempts still available to this operation.

pub fn consume(&mut self, count: usize) -> Result<(), XmlEncError>

Charge attempted candidate work before performing it.

Trait Implementations

impl Debug for KeyCandidateBudget

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

Formats the value using the given formatter.
