Enum MetricsError 

pub enum MetricsError {
    Sqlite(Error),
    Chrono(ParseError),
    Io(Error),
    Task(String),
    InvalidData(String),
}

Errors that can occur during metrics storage operations.

This enum covers all the error cases that can arise when working with the metrics storage system, from database errors to data validation issues.

Variants

Sqlite(Error)

SQLite database operation failed.

This can occur due to SQL syntax errors, constraint violations, database corruption, or connection issues.

Chrono(ParseError)

Timestamp parsing failed.

This occurs when reading timestamps from the database that don’t conform to the expected RFC3339 format.

Io(Error)

I/O operation failed.

This can occur when creating the database file, directory, or during other file system operations.

Task(String)

Async task failed to complete.

This occurs when a spawned blocking task panics or is cancelled, typically indicating a serious system issue.

InvalidData(String)

Data validation failed.

This occurs when retrieved data doesn’t match expected constraints, such as invalid enum values or malformed data.

Trait Implementations

impl Debug for MetricsError

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

Formats the value using the given formatter.

impl Display for MetricsError

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

Formats the value using the given formatter.

impl Error for MetricsError

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
