CallContextWithCx

Struct CallContextWithCx 

Source
pub struct CallContextWithCx<'a> { /* private fields */ }
Expand description

Call context with an attached capability context.

This wrapper is intended for framework integrations that need to thread Cx through gRPC handlers while retaining the base call metadata.

use asupersync::cx::cap::CapSet;
use asupersync::grpc::CallContext;

type GrpcCaps = CapSet<true, true, false, false, false>;

fn handle(ctx: &CallContext, cx: &asupersync::Cx) {
    let ctx = ctx.with_cx(cx);
    let limited = ctx.cx_narrow::<GrpcCaps>();
    limited.checkpoint().ok();
}

Implementations§

Source§

impl CallContextWithCx<'_>

Source

pub fn call(&self) -> &CallContext
