pub struct ParseError {
    pub message: Cow<'static, str>,
    pub input: Option<BString>,
}

An error occurred when parsing input

Fields

message: Cow<'static, str>

The error message.

input: Option<BString>

The input or portion of the input that failed to parse.

Implementations

impl ParseError

Lifecycle

pub fn new_with_input( message: impl Into<Cow<'static, str>>, input: impl Into<BString>, ) -> Self

Create a new error with message and input. Note that input isn’t printed.

pub fn new(message: impl Into<Cow<'static, str>>) -> Self

Create a new instance that displays the given message.

Trait Implementations

impl Debug for ParseError

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

Formats the value using the given formatter.

impl Display for ParseError

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

Formats the value using the given formatter.

impl Error for ParseError

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.

Converts to this type from the input type.

impl From<Message> for ParseError

fn from(Message: Message) -> Self

Converts to this type from the input type.

impl From<String> for ParseError

fn from(msg: String) -> Self
