Struct RangeExprError 

pub struct RangeExprError {
    pub expr: String,
    pub message: String,
    pub position: Option<usize>,
}

Error raised when parsing a range expression fails.

Fields

expr: String

message: String

position: Option<usize>

Implementations

impl RangeExprError

pub fn new(expr: impl Into<String>, message: impl Into<String>) -> Self

pub fn at( expr: impl Into<String>, message: impl Into<String>, position: usize, ) -> Self

Trait Implementations

impl Clone for RangeExprError

fn clone(&self) -> RangeExprError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RangeExprError

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

Formats the value using the given formatter.

impl Display for RangeExprError

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

Formats the value using the given formatter.

impl Error for RangeExprError

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<RangeExprError> for ExpressionError

fn from(e: RangeExprError) -> Self

Lift a range-expression parse error into an ExpressionError.

If the error carries a position, attach the source string with a span covering the single character at that offset so the standard caret renderer points at the failure. Without a position, fall back to the stringified Display form.
