Struct serde_lexpr::parse::error::Error

pub struct Error { /* fields omitted */ }

This type represents the possible errors when parsing S-expression data.

Methods

impl Error

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

Location of the error in the input stream.

pub fn classify(&self) -> Category

Categorizes the cause of this error.

• Category::Io - failure to read or write bytes on an IO stream
• Category::Syntax - input that is not a syntactically valid S-experssion
• Category::Eof - unexpected end of the input data

pub fn is_io(&self) -> bool

Returns true if this error was caused by a failure to read or write bytes on an IO stream.

pub fn is_syntax(&self) -> bool

Returns true if this error was caused by input that was not a syntactically valid S-expression.

pub fn is_eof(&self) -> bool

Returns true if this error was caused by prematurely reaching the end of the input data.

Callers that process streaming input may be interested in retrying the deserialization once more data is available.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for Error

fn from(e: Error) -> Self

Performs the conversion.
