Struct DesignationContext 

pub struct DesignationContext {
    pub subject: ObjectId,
    pub args: Option<Value>,
    /* private fields */
}

Per-call context handed to a DesignationResolver.

The typed core (subject, args) covers the most common shapes; the extension bag carries anything else the caller wants to make available to resolvers, keyed by Rust type. A WebappResolver, for instance, reads its session via ctx.get::<AuthSession>() where AuthSession is whatever the consuming application defines.

Fields

subject: ObjectId

The principal that will be the subject of the minted capability.

args: Option<Value>

Per-call arguments (e.g., the JSON body of a tool invocation).

Implementations

impl DesignationContext

pub fn new(subject: ObjectId) -> Self

Build a context for a subject. Args and extensions are unset; chain Self::with_args and Self::insert as needed.

pub fn with_args(self, args: Value) -> Self

Attach per-call arguments (consuming the context).

pub fn insert<T: Any + Send + Sync>(&mut self, ext: T)

Insert a typed extension. Replaces any existing value of the same type.

pub fn get<T: Any + Send + Sync>(&self) -> Option<&T>

Fetch a typed extension by its concrete type.

Trait Implementations

impl Debug for DesignationContext

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

Formats the value using the given formatter.
