Struct Block 

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

One block of a system prompt.

Anthropic accepts a system prompt as either a string or a list of {type: "text", text, cache_control?} blocks. We model the block form directly; conversion from a plain string is handled by to_system_blocks and the From impls.

Fields

text: String

The block’s text content.

cache_control: Option<CacheControl>

Optional cache_control marker. Some(CacheControl::Ephemeral) means the block ends a cacheable prefix.

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Block

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<&str> for Block

fn from(text: &str) -> Self

Converts to this type from the input type.

impl From<String> for Block

fn from(text: String) -> Self

Converts to this type from the input type.

impl PartialEq for Block

fn eq(&self, other: &Block) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
