Struct substrait_validator::output::diagnostic::Cause

pub struct Cause {
    pub message: Arc<Message>,
    pub classification: Classification,
}

Description of the cause of a diagnostic.

Fields

message: Arc<Message>

The error message. Within this crate we don’t bother typing these beyond the Classification enum, but we do retain typing information for messages from other crates.

classification: Classification

Classification of this cause. This attaches an error code and generic message for said code to the diagnostic message. The user can use these codes to for instance always promote a particular type of diagnostic to an error (like gcc -Werror).

Trait Implementations

impl Clone for Cause

fn clone(&self) -> Cause

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cause

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

Formats the value using the given formatter.

impl Display for Cause

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

Formats the value using the given formatter.

impl Error for Cause

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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

impl PartialEq<Cause> for Cause

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
