Struct ListerCapabilities 

pub struct ListerCapabilities {
    pub sort: OptionSupport,
    pub offset: OptionSupport,
    pub before: OptionSupport,
    pub after: OptionSupport,
    pub limit: OptionSupport,
}

Declared native support for a lister program’s optional operations.

Supply this separately from ListerOptions: requests and native support are independent. Default and an empty builder leave all capabilities Unknown. Output-format support is not configured here. A host may obtain these declarations from module metadata or other knowledge of the program; this crate performs no discovery. Concrete forwarding and fallback policies belong to the executor.

use asimov_patterns::{ListerCapabilities, OptionSupport};

let capabilities = ListerCapabilities::builder()
    .sort(OptionSupport::Unsupported)
    .offset(OptionSupport::Supported)
    .limit(OptionSupport::Unsupported)
    .after(OptionSupport::Supported)
    .build();
assert_eq!(capabilities.sort, OptionSupport::Unsupported);
assert_eq!(capabilities.offset, OptionSupport::Supported);
assert_eq!(capabilities.limit, OptionSupport::Unsupported);
assert_eq!(capabilities.after, OptionSupport::Supported);
assert_eq!(ListerCapabilities::builder().build(), ListerCapabilities::default());
assert_eq!(ListerCapabilities::default().sort, OptionSupport::Unknown);

Fields

sort: OptionSupport

Native --sort support. Supported sort keys and RDF mapping profiles still depend on the program; this flag does not define a sorting grammar.

offset: OptionSupport

Native --offset support, applied after sorting and before limiting.

before: OptionSupport

Native --before support for an exclusive entry-ID cursor bound.

after: OptionSupport

Native --after support for an exclusive entry-ID cursor bound.

limit: OptionSupport

Native --limit support. A host can omit an unsupported native limit while still enforcing the requested result count locally.
