Struct SessionCtx 

#[non_exhaustive]
pub struct SessionCtx {
    pub ext: Option<Arc<dyn Any + Send + Sync>>,
}

The authenticated session context produced by Dispatch::authenticate and threaded into Dispatch::open.

Carries the resolved principal as a type-erased ext for per-operation authorization in the Session; downcast with ext_as. Connectors that don’t authenticate leave it None.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

ext: Option<Arc<dyn Any + Send + Sync>>

The resolved principal, type-erased. Downcast with ext_as.

Implementations

impl SessionCtx

pub fn with_ext(ext: Arc<dyn Any + Send + Sync>) -> Self

Build a context carrying a connector-resolved principal.

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

Downcast the ext principal to a concrete connector type.
