Struct SystemBlock 

pub struct SystemBlock {
    pub kind: &'static str,
    pub text: String,
    pub cache_control: Option<CacheControl>,
}

One block of an Anthropic system array.

We only ever send type: "text". The cache_control field is conditionally serialized — when None, it’s omitted from the wire JSON (skip_serializing_if), so a non-cached request and a cached request produce different bytes — that difference is the cache key.

Fields

kind: &'static str

text: String

cache_control: Option<CacheControl>
