Enum guppy::TargetSpecError

#[non_exhaustive]pub enum TargetSpecError {
    InvalidCfg(ParseError),
    UnknownTargetTriple(String),
    UnknownPlatformTriple(String),
    UnknownPredicate(String),
    CustomPlatformSummary,
}

An error that happened during target-spec parsing or 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.

InvalidCfg(ParseError)

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

UnknownTargetTriple(String)

The provided target triple (in the position that a cfg() expression would be) was unknown.

UnknownPlatformTriple(String)

The provided platform triple was unknown.

UnknownPredicate(String)

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

CustomPlatformSummary

Attempt to generate summary from custom platform.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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

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

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

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

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl PartialEq<Error> for Error

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

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

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

This method tests for !=.
