Enum cnf_lib::provider::Error

pub enum Error {
    NotFound(String),
    Requirements(String),
    ApplicationError(Error),
    NotImplemented(String),
    Execution(ExecutionError),
}

Variants

NotFound(String)

Requested executable couldn’t be found.

Return this error if the executable that cnf is queried for cannot be found in a provider. If the provider has other issues (i.e. a certain package manager isn’t present), return a Requirements error instead.

Requirements(String)

Provider requirements aren’t fulfilled (e.g. some binary/package manager is missing).

Please provide a human-readable, actionable description of what the respective provider requires.

ApplicationError(Error)

Transparent error from any source.

NotImplemented(String)

Required feature not implemented yet.

Execution(ExecutionError)

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

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
