Struct ProgressTracker 

pub struct ProgressTracker { /* private fields */ }

A helper for sending progress updates for a long-running operation.

This wraps a NotificationSender and an optional progress token, making it easy to report progress without checking if the token is present each time.

Implementations

impl ProgressTracker

pub fn new(notifier: NotificationSender, token: Option<ProgressToken>) -> Self

Create a new progress tracker.

If token is None, all progress updates will be no-ops.

pub fn from_meta(notifier: NotificationSender, meta: Option<&Value>) -> Self

Create a tracker from a request’s _meta.progressToken.

Extracts the progress token from the _meta field of a request params object.

pub async fn update(&self, progress: f64, total: f64, message: Option<String>)

Send a progress update.

• progress: Current progress value
• total: Total value (progress/total gives percentage)
• message: Optional status message

Returns silently if no progress token was provided.

pub async fn update_percent(&self, percent: f64, message: Option<String>)

Send a progress update with just a percentage (0.0 to 1.0).

pub async fn update_with_message( &self, progress: f64, total: f64, message: impl Into<String>, )

Send a progress update with a message.

pub async fn complete(&self, message: impl Into<String>)

Mark the operation as complete with a final message.

pub fn is_tracking(&self) -> bool

Check if progress tracking is enabled (token was provided).
