Struct WebappResolver 

pub struct WebappResolver { /* private fields */ }

A resolver designed for the webapp pattern. Pulls designation values from two sources, both supplied via context extensions:

• AuthSession for fields the webapp authenticated (tenant, user, etc.).
• RequestUrl for path segments matched by {name} placeholder patterns.

Both sources are optional per target. The resolver returns whatever it can successfully extract; configured fields that are missing in the session, or URL patterns that don’t match the request URL, return ResolverError::MissingField / ResolverError::InvalidShape.

Example

use hessra_cap_engine::WebappResolver;

let resolver = WebappResolver::builder()
    .for_target("api:posts")
    .from_session("tenant_id", "tenant_id")
    .from_session("user", "user_subject")
    .from_url_pattern("/tenants/{tenant_id}/posts/{resource_id}")
    .build();
