Implementations

impl LnmpError

pub fn with_context(self, _context: ErrorContext) -> Self

Adds error context with source snippet

pub fn format_with_source(&self, source: &str) -> String

Formats the error with source context for rich error messages

pub fn position(&self) -> (usize, usize)

Returns the line and column position of the error

Trait Implementations

impl Clone for LnmpError

fn clone(&self) -> LnmpError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LnmpError

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

Formats the value using the given formatter.

impl Display for LnmpError

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

Formats the value using the given formatter.

impl Error for LnmpError

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<LnmpError> for BinaryError

fn from(err: LnmpError) -> Self

Converts to this type from the input type.

impl PartialEq for LnmpError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
