Implementations

impl YamlError

pub fn location(&self) -> Option<&Location>

Returns the location of the error, if available.

pub fn snippet(&self) -> Option<&str>

Returns the code snippet, if available.

pub fn path(&self) -> Option<&str>

Returns the path where the error occurred, if applicable.

pub fn suggestions(&self) -> Vec<String>

Returns helpful suggestions for fixing the error.

Trait Implementations

impl Clone for YamlError

fn clone(&self) -> YamlError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for YamlError

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

Formats the value using the given formatter.

impl Display for YamlError

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

Formats the value using the given formatter.

impl Error for YamlError

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<&str> for YamlError

fn from(err: &str) -> Self

Converts to this type from the input type.

impl From<Error> for YamlError

fn from(err: Error) -> Self

Converts to this type from the input type.

impl From<LexError> for YamlError

fn from(err: LexError) -> Self

Converts to this type from the input type.

impl From<String> for YamlError

fn from(err: String) -> Self

Converts to this type from the input type.

impl PartialEq for YamlError

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