Enum RrdError

pub enum RrdError {
    NulError(NulError),
    PathEncodingError,
    LibRrdError(String),
    Internal(String),
    InvalidArgument(String),
}

Top-level RRD error used for all librrd operations.

Variants

NulError(NulError)

A string contained \0, and thus could not be converted to a C string

PathEncodingError

A path contained non-UTF-8 data

LibRrdError(String)

An error from the underlying C librrd library

Internal(String)

A miscellaneous error in this library

InvalidArgument(String)

An InvalidArgument error

Trait Implementations

impl Debug for RrdError

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

Formats the value using the given formatter.

impl Display for RrdError

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

Formats the value using the given formatter.

impl Error for RrdError

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 From<InvalidArgument> for RrdError

fn from(value: InvalidArgument) -> Self

Converts to this type from the input type.

impl From<NulError> for RrdError

fn from(source: NulError) -> Self

Converts to this type from the input type.

impl PartialEq for RrdError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
