Represents all reasons pkg-config might not succeed or be run at all.

Variants

EnvNoPkgConfig(String)

Aborted because of *_NO_PKG_CONFIG environment variable.

Contains the name of the responsible environment variable.

CrossCompilation

Detected cross compilation without a custom sysroot.

Ignore the error with PKG_CONFIG_ALLOW_CROSS=1, which may let pkg-config select libraries for the host’s architecture instead of the target’s.

Command

cause: Error

Failed to run pkg-config.

Contains the command and the cause.

Failure

Fields

command: String

pkg-config did not exit sucessfully after probing a library.

Contains the command and output.

ProbeFailure

Fields

name: String

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

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 self, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.
