Struct StreamPrinter 

struct StreamPrinter {
    enabled: bool,
    color: Style,
    started: bool,
    last_was_newline: bool,
}

Streams a subprocess backend’s assistant text and reasoning to stdout as the CLI emits it, mirroring the openai backend. This is chunk-level: each CLI event (text block / part / item) is printed whole as it arrives, not token-by-token. Reasoning is dimmed to set it apart from the answer. Tool-call lines are printed separately to stderr and are not handled here.

Fields

enabled: bool

color: Style

started: bool

last_was_newline: bool

Implementations

impl StreamPrinter

fn new(enabled: bool, color: Style) -> Self

fn emit(&mut self, to_print: &str, raw: &str) -> Result<()>

fn text(&mut self, s: &str) -> Result<()>

Assistant answer/plan text, printed verbatim.

fn reasoning(&mut self, s: &str) -> Result<()>

Reasoning / thinking, dimmed to distinguish it from the answer. Trailing newline is tracked from the raw text, not the styled (ANSI-wrapped) string.

fn newline(&mut self)

End the current line if the last chunk did not already. Use after a whole-block event (claude/codex) so consecutive blocks don’t run together; also called once at the end via [finish].

fn finish(&mut self)
