Struct SystemBlock 

pub struct SystemBlock {
    pub text: String,
    pub cache_control: Option<CacheControl>,
}

One text block in a structured system prompt.

Serializes to the Anthropic API shape {"type":"text","text":"..."}, plus a cache_control entry when one is set. Only the text block is modelled, which mirrors ContentBlock::Text and matches the block the API documents for a system prompt; any extra field on deserialization is ignored rather than rejected, so a block that grows new fields still parses.

Fields

text: String

The block text.

cache_control: Option<CacheControl>

An optional prompt-cache marker. When set, the API caches the request prefix up to and including this block.

Implementations

impl SystemBlock

pub fn text(text: impl Into<String>) -> SystemBlock

A system text block with no cache marker.

pub fn with_cache_control(self, cache_control: CacheControl) -> SystemBlock

Attach a cache-control marker to this block.
