Enum target_spec::ParseError

#[non_exhaustive]pub enum ParseError {
    InvalidCfg(String),
    UnknownTriple(String),
    UnknownPredicate(String),
}

An error that occurred while attempting to parse a target specification.

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.

InvalidCfg(String)

This cfg() expression was invalid and could not be parsed.

UnknownTriple(String)

The provided target triple was unknown.

UnknownPredicate(String)

The provided cfg() expression parsed correctly, but it had an unknown predicate.

Trait Implementations

impl Clone for ParseError

fn clone(&self) -> ParseError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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<ParseError> for ParseError

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

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

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

This method tests for !=.
