pub struct BindingChainException { /* private fields */ }

An error that signals that a binding chain is broken: the value could not be read at some point of the binding path.

Implementations

impl BindingChainException

pub fn new() -> Self

pub fn with_message(message: impl Into<String>) -> Self

pub fn with_expression( message: impl Into<String>, expression: impl Into<String>, error_point: impl Into<String>, ) -> Self

pub fn expression(&self) -> Option<&str>

The expression that could not be evaluated.

pub fn set_expression(&mut self, value: Option<String>)

Sets the expression that could not be evaluated (the protected setter of Expression).

pub fn expression_error_point(&self) -> Option<&str>

The point in the expression at which the error occurred.

pub fn set_expression_error_point(&mut self, value: Option<String>)

Sets the point in the expression at which the error occurred (the protected setter of ExpressionErrorPoint).

pub fn message(&self) -> String

The full message, including the expression and error point.

Trait Implementations

impl Clone for BindingChainException

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BindingChainException

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

Formats the value using the given formatter.

impl Default for BindingChainException

fn default() -> Self

Returns the “default value” for a type.

impl Display for BindingChainException

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

Formats the value using the given formatter.

impl Error for BindingChainException

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.
