Rich query error with context and suggestions

Fields

message: String

Error message

sql: String

The SQL query that caused the error

line: usize

Line number where error occurred (1-indexed)

column: usize

Column number where error occurred (1-indexed)

suggestion: Option<String>

Suggested fix for the error

help: Option<String>

Additional help text

span_length: usize

Length of the error span (for underlining)

Implementations

impl QueryError

pub fn new( message: impl Into<String>, sql: impl Into<String>, line: usize, column: usize, ) -> Self

Create a new query error

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

Add a suggestion

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

Add help text

pub fn with_span(self, length: usize) -> Self

Set the span length for underlining

pub fn format_with_context(&self) -> String

Format the error with source context

Trait Implementations

impl Clone for QueryError

fn clone(&self) -> QueryError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QueryError

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

Formats the value using the given formatter.

impl Display for QueryError

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

Formats the value using the given formatter.

impl Error for QueryError

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.

impl From<QueryError> for Error

fn from(source: QueryError) -> Self

Converts to this type from the input type.
