Struct Error

#[non_exhaustive]
pub struct Error {
    pub(crate) kind: NetdocErrorKind,
    msg: Option<Cow<'static, str>>,
    pos: Pos,
    source: Option<NetdocErrorSource>,
}

An error that occurred while parsing a directory object of some kind.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

kind: NetdocErrorKind

What kind of error occurred?

msg: Option<Cow<'static, str>>

Do we have more information about the error?>

pos: Pos

Where did the error occur?

source: Option<NetdocErrorSource>

Was this caused by another error?

Implementations

impl Error

pub(crate) fn pos(&self) -> Pos

Helper: return this error’s position.

pub fn within(self, s: &str) -> Error

Return a new error based on this one, with any byte-based position mapped to some line within a string.

pub fn at_pos(self, p: Pos) -> Error

Return a new error based on this one, with the position (if any) replaced by ‘p’.

pub fn or_at_pos(self, p: Pos) -> Error

Return a new error based on this one, with the position (if replaced by ‘p’ if it had no position before.

pub(crate) fn with_msg<T>(self, message: T) -> Error

where T: Into<Cow<'static, str>>,

Return a new error based on this one, with the message value set to a provided static string.

pub(crate) fn with_source<T>(self, source: T) -> Error

where T: Into<NetdocErrorSource>,

Return a new error based on this one, with the source-error value set to the provided error.

pub fn netdoc_error_kind(&self) -> NetdocErrorKind

Return the NetdocErrorKind of this error.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for Error

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<AddrParseError> for Error

fn from(source: AddrParseError) -> Error

Converts to this type from the input type.

impl From<Bug> for Error

fn from(err: Bug) -> Self

Converts to this type from the input type.

impl From<Error> for BuildError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Error

Converts to this type from the input type.

impl From<ParseIntError> for Error

fn from(source: ParseIntError) -> Error

Converts to this type from the input type.

impl From<PolicyError> for Error

fn from(source: PolicyError) -> Error

Converts to this type from the input type.

impl From<TimeValidityError> for Error

fn from(source: TimeValidityError) -> Error

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Self) -> 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.
