Enum target_spec::EvalError

#[non_exhaustive]pub enum EvalError {
    InvalidSpec(ParseError),
    PlatformNotFound,
}

An error that occurred during target evaluation.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidSpec(ParseError)

An invalid target spec was specified.

PlatformNotFound

The platform was not found in the database.

Trait Implementations

impl Debug for EvalError

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

Formats the value using the given formatter.

impl Display for EvalError

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

Formats the value using the given formatter.

impl Error for EvalError

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()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl PartialEq<EvalError> for EvalError

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
