Variants

PkgConfig(Error)

pkg-config error

BuildInternalClosureError(String, BuildInternalClosureError)

One of the Config::add_build_internal closures failed

FailToRead(String, Error)

Failed to read Cargo.toml

InvalidMetadata(String)

Raised when an error is detected in the metadata defined in Cargo.toml

MissingLib(String)

Raised when dependency defined manually using SYSTEM_DEPS_$NAME_NO_PKG_CONFIG did not define at least one lib using SYSTEM_DEPS_$NAME_LIB or SYSTEM_DEPS_$NAME_LIB_FRAMEWORK

BuildInternalInvalid(String)

An environment variable in the form of SYSTEM_DEPS_$NAME_BUILD_INTERNAL contained an invalid value (allowed: auto, always, never)

BuildInternalNoClosure(String, String)

system-deps has been asked to internally build a lib, through SYSTEM_DEPS_$NAME_BUILD_INTERNAL=always' or SYSTEM_DEPS_$NAME_BUILD_INTERNAL=auto', but not closure has been defined using Config::add_build_internal to build this lib

BuildInternalWrongVersion(String, String, String)

The library which has been build internally does not match the required version defined in Cargo.toml

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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 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 From<Error> for Error

fn from(source: Error) -> Self

Performs the conversion.
