Struct FetchRequest 

pub struct FetchRequest {
    pub source_name: Option<String>,
    pub spec: InlineData,
    pub cache: Option<CacheConfig>,
    pub headers: HashMap<String, String>,
    pub namespace: Option<String>,
    pub cancel_token: Option<CancellationToken>,
}

Per-source request context. Carries the resolved spec (params already substituted) plus cache + header + namespace + cancellation hints.

Fields

source_name: Option<String>

User-chosen name for this source within the chart spec. None for unnamed (flat) data: forms.

spec: InlineData

Fully resolved flat-form source spec — datasource, query, url, rows, etc. with $param.name references already substituted.

cache: Option<CacheConfig>

Parsed cache config from spec.cache.ttl (and auto_refresh).

headers: HashMap<String, String>

Request-level HTTP headers (merged with HttpProvider defaults). Ignored by non-HTTP providers unless they explicitly read this field.

namespace: Option<String>

Tenant / workspace namespace folded into the cache key. None for single-tenant deployments.

cancel_token: Option<CancellationToken>

Optional cancellation token. Phase 3 always passes None from the resolver; providers that opt into honoring it stay forward-compatible with future tab-close / cancel-on-route-change wiring.
