Struct ConstraintContext 

pub struct ConstraintContext {
    pub purpose: Option<String>,
    pub now: Option<DateTime<Utc>>,
    pub custom: HashMap<String, String>,
}

Context provided when evaluating constraints.

The context carries all information about the current request that constraints might need to evaluate. Add fields here as your policies grow.

Fields

purpose: Option<String>

The purpose of this access request (e.g., "analytics", "audit").

now: Option<DateTime<Utc>>

The current time (defaults to Utc::now() if not specified).

custom: HashMap<String, String>

An arbitrary key-value store for custom constraint operands.

Implementations

impl ConstraintContext

pub fn with_purpose(self, purpose: impl Into<String>) -> Self

Create a context with a given purpose.

pub fn with_time(self, t: DateTime<Utc>) -> Self

Create a context with a specific time (useful for testing).

pub fn with(self, key: impl Into<String>, value: impl Into<String>) -> Self

Add a custom key-value pair.
