Enum CfgPathError 

#[non_exhaustive]
pub enum CfgPathError {
    UnknownVar(String),
    NoProjectDirs,
    NoBaseDirs,
    NoProgramPath,
    NoProgramDir,
    InvalidString(String),
    VariableInterpolationNotSupported(String),
    HomeDirInterpolationNotSupported(String),
}

An error that has occurred while expanding a path.

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.

UnknownVar(String)

The path contained a variable we didn’t recognize.

NoProjectDirs

We couldn’t construct a ProjectDirs object.

NoBaseDirs

We couldn’t construct a BaseDirs object.

NoProgramPath

We couldn’t find our current binary path.

NoProgramDir

We couldn’t find the directory path containing the current binary.

InvalidString(String)

We couldn’t convert a string to a valid path on the OS.

VariableInterpolationNotSupported(String)

Variable interpolation ($) attempted, but not compiled in

HomeDirInterpolationNotSupported(String)

Home dir interpolation (~) attempted, but not compiled in

Trait Implementations

impl Clone for CfgPathError

fn clone(&self) -> CfgPathError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CfgPathError

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

Formats the value using the given formatter.

impl Display for CfgPathError

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

Formats the value using the given formatter.

impl Error for CfgPathError

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

Returns 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>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl HasKind for CfgPathError

fn kind(&self) -> ErrorKind

Return the kind of this error.
