Struct Error 

pub struct Error(/* private fields */);

Represents an error with additional location information.

Implementations

impl Error

pub fn new<T>( error: T, file: &'static str, line: u32, func: &'static str, module: &'static str, ) -> Self

where T: Into<Box<dyn Error + Send + Sync>>,

Creates a new Error with location information.

Parameters

• error: The error to wrap.
• file: The file where the error occurred.
• line: The line number where the error occurred.
• func: The function where the error occurred.
• module: The module where the error occurred.

pub fn plain<T>(error: T) -> Self

where T: Into<Box<dyn Error + Send + Sync>>,

Creates a new Error without location information.

pub fn chain<T>( error: T, file: &'static str, line: u32, func: &'static str, module: &'static str, ) -> Self

where T: Error + Send + Sync + 'static,

Chains an error with additional location information.

If the provided error is not of type Error, it creates a new Error with location information. If the provided error is of type Error, it adds the location information if it was not created by Error::plain.

Parameters

• error: The error to wrap.
• file: The file where the error occurred.
• line: The line number where the error occurred.
• func: The function where the error occurred.
• module: The module where the error occurred.

pub fn context(self, context: impl ToString) -> Self

pub fn location(&self) -> Option<&[Location]>

Returns the location information.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
