Struct StreamingTextState 

pub struct StreamingTextState {
    pub content: String,
    pub streaming: bool,
    /* private fields */
}

State for a streaming text display.

Accumulates text chunks as they arrive from an LLM stream. Pass to Context::streaming_text each frame.

Fields

content: String

The accumulated text content.

streaming: bool

Whether the stream is still receiving data.

Implementations

impl StreamingTextState

pub fn new() -> Self

Create a new empty streaming text state.

pub fn push(&mut self, chunk: &str)

Append a chunk of text (e.g., from an LLM stream delta).

pub fn finish(&mut self)

Mark the stream as complete (hides the typing cursor).

pub fn start(&mut self)

Start a new streaming session, clearing previous content.

pub fn clear(&mut self)

Clear all content and reset state.

pub fn version(&self) -> u64

Monotonic version counter, bumped on every content mutation (push / start / clear).

The stream itself changes every token, so this value is not a useful cache key for the streaming region. Its purpose is the inverse: it lets you detect when the stream did change so you can decide whether the surrounding static chrome is stable. Combine a hash of your non-streaming inputs into a key for ContainerBuilder::cached and wrap the chrome — not the stream — in it.

Since 0.21.0.

Example

let mut stream = slt::StreamingTextState::new();
stream.push("hello");
assert_eq!(stream.version(), 1);
stream.push(" world");
assert_eq!(stream.version(), 2);
