Struct FrameworkError 

pub struct FrameworkError {
    pub severity: Severity,
    pub source: ErrorSource,
    pub message: String,
    pub context: Option<String>,
}

Error from egui-cha framework internals

This type represents errors that occur within the framework itself, such as task panics, runtime failures, or subscription errors.

Example

fn on_framework_error(model: &mut Model, err: FrameworkError) -> Cmd<Msg> {
    // Add to your error console
    model.errors.push_with_level(&err.message, err.severity.into());

    // Or handle specific sources differently
    match err.source {
        ErrorSource::Command => { /* retry logic */ }
        _ => { /* log and continue */ }
    }
    Cmd::none()
}

Fields

severity: Severity

Error severity

source: ErrorSource

Error source/category

message: String

Error message

context: Option<String>

Optional context (additional details)

Implementations

impl FrameworkError

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

Add context to the error

pub fn command(severity: Severity, message: impl Into<String>) -> Self

Create a command error

pub fn runtime(severity: Severity, message: impl Into<String>) -> Self

Create a runtime error

pub fn subscription(severity: Severity, message: impl Into<String>) -> Self

Create a subscription error

pub fn view(severity: Severity, message: impl Into<String>) -> Self

Create a view error

pub fn log(&self)

Log this error to tracing

pub fn format_message(&self) -> String

Trait Implementations

impl Clone for FrameworkError

fn clone(&self) -> FrameworkError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FrameworkError

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

Formats the value using the given formatter.

impl Display for FrameworkError

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

Formats the value using the given formatter.

impl Error for FrameworkError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
