The fundamental error type for the evaluation engine. These cases represent different kinds of errors the evaluator might face, along with helpful spans to label. An error renderer will take this error value and pass it into an error viewer to display to the user.

Trait Implementations

impl Clone for ShellError

fn clone(&self) -> ShellError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ShellError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ShellError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Diagnostic for ShellError

fn code<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

Unique diagnostic code that can be used to look up more information about this Diagnostic. Ideally also globally unique, and documented in the toplevel crate’s documentation for easy searching. Rust path format (foo::bar::baz) is recommended, but more classic codes like E0123 or enums will work just fine.

fn help<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

Additional help text related to this Diagnostic. Do you have any advice for the poor soul who’s just run into this issue?

fn labels(&self) -> Option<Box<dyn Iterator<Item = LabeledSpan>>>

Labels to apply to this Diagnostic’s Diagnostic::source_code

fn source_code(&self) -> Option<&dyn SourceCode>

Source code to apply this Diagnostic’s Diagnostic::labels to.

fn related(&self) -> Option<Box<dyn Iterator<Item = &dyn Diagnostic>>>

Additional related Diagnostics.

fn url<'a>(&'a self) -> Option<Box<dyn Display + 'a>>

URL to visit for a more detailed explanation/help about this Diagnostic.

fn severity(&self) -> Option<Severity>

Diagnostic severity. This may be used by ReportHandlers to change the display format of this diagnostic.

impl Display for ShellError

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

Formats the value using the given formatter.

impl Error for ShellError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<Box<dyn Error + 'static, Global>> for ShellError

fn from(input: Box<dyn Error>) -> ShellError

Converts to this type from the input type.

impl From<Box<dyn Error + Sync + Send + 'static, Global>> for ShellError

fn from(input: Box<dyn Error + Send + Sync>) -> ShellError

Converts to this type from the input type.

impl From<Error> for ShellError

fn from(input: Error) -> ShellError

Converts to this type from the input type.

impl Serialize for ShellError

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.
