Struct relp::io::error::Parse

pub struct Parse { /* fields omitted */ }

A ParseError represents all errors encountered during parsing.

It may recursively hold more ParseErrors to provide more detail. At the end of this chain, there may be a file location containing a line number and line, at which the error was caused.

Implementations

impl Parse

pub fn new(description: impl Into<String>) -> Self

Create a new ParseError with only a description.

Arguments

• description: What’s wrong at the moment of creation.

Return value

• A ParseError instance without a cause.

pub fn with_location(
    description: impl Into<String>,
    file_location: (usize, &'_ str)
) -> Self

Create a new ParseError instance with a FileLocation as a cause.

Arguments

• description: What’s wrong at the moment of creation.
• file_location: A reference to a line number and line that caused the error.

Return value

A new ParseError instance with a FileLocation cause.

pub fn wrap(self, description: impl Into<String>) -> Self

Wrap a description into a parse error.

pub fn wrap_other(
    source: impl Error + 'static,
    description: impl Into<String>
) -> Self

Wrap a new ParseError around an existing one.

Arguments

• description: What’s wrong at the moment of creation.
• parse_error: What caused this ParseError.

Return value

A new ParseError instance with a ParseError cause.

Trait Implementations

impl Debug for Parse

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

Formats the value using the given formatter.

impl Display for Parse

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

Formats the value using the given formatter.

impl Error for Parse

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

Find out what caused this error.

Return value

Option<&Error> which may be a ParseErrorCause.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

Describe this error.

Return value

The description as a &str.

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Parse> for Import

fn from(error: Parse) -> Self

Performs the conversion.
