Struct dontpanic::Builder

pub struct Builder { /* private fields */ }

A builder to configure dontpanic behavior.

Use the builder method in to root of this crate to create this type.

Implementations

impl Builder

pub fn environment(self, name: impl Into<String>) -> Self

Set the reported environment. Useful for separating reports originating on dev and staging environments from production reports. You can use debug_assertions to set this, or environment variables set by a CI pipeline.

use anyhow::Result;

fn main() -> Result<()> {
    dontpanic::builder("<PROJECT_API_KEY>")
        .environment(if cfg!(debug_assertions) {
            "development"
        } else {
            "production"
        })
        .build()?;

    Ok(())
}

pub fn version(self, version: impl Into<String>) -> Self

Set your application version. Use this to track when a panic! or error! first occurred and consequently, when it is resolved.

If application version tracking is done via Cargo.toml, the current version can be obtained via CARGO_PKG_VERSION env var:

fn main() -> Result<()> {
    dontpanic::builder("<PROJECT_API_KEY>")
        .version(env!("CARGO_PKG_VERSION"))
        .build()?;

    Ok(())
}

pub fn backend_url(self, url: String) -> Self

Controls where reports are sent to.

Set this to point to the backend server url where you want to send reports. For more information see Don’t Panic Server documentation.

pub fn send_report_on_log_errors(self, enabled: bool) -> Self

Available on crate features tracing and log only.

Enabled by default. log::error!, tracing::error! and tracing::event!(Level::ERROR, ... will trigger a report to be sent to the configured backend server.

pub fn build(self) -> Result<Client, Error>

Builds a Client that can be used to interact with this library.

This method registers a custom panic hook. The default rust hook, that prints a message to standard error and generates a backtrace is still invoked when a panic occurs.
