Fields

model: Option<String>

Model that produced the answer.

chunks: Option<usize>

Number of retrieved chunks that entered the prompt.

sources: Vec<SourceRef>

tokens: Option<usize>

elapsed: Option<Duration>

Wall-clock generation time.

Implementations

impl MessageMeta

pub fn summary(&self) -> String

One-line summary, e.g. deepseek-chat · 12 chunks · 3 sources · 421 tokens · 8.2 s.

Source titles are rendered separately as chips, so only their count is included here.

pub fn is_empty(&self) -> bool

Returns whether the footer has anything to show.

pub fn add_source(&mut self, source: SourceRef) -> bool

Add a source unless one with the same SourceRef::id is present.

Returns whether the source was added.

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

Performs copy-assignment from source.

impl Debug for MessageMeta

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

Formats the value using the given formatter.

impl Default for MessageMeta

fn default() -> Self
