Struct mshio::error::MshParserError

pub struct MshParserError<I> {
    pub backtrace: Vec<(I, MshParserErrorKind)>,
}

Error type returned by the crate when parsing fails

Fields

backtrace: Vec<(I, MshParserErrorKind)>

Error backtrace that contains per level a reference into the input where the error ocurred and the corresponding error kind

Implementations

impl<I> MshParserError<I>

pub fn begin_msh_errors(&self) -> impl Iterator<Item = &(I, MshParserErrorKind)>

Iterator that skips all errors in the beginning of the backtrace that are not actual MSH format errors (i.e. internal nom parser errors)

pub fn filter_msh_errors(
    &self
) -> impl Iterator<Item = &(I, MshParserErrorKind)>

Iterator over all errors in the backtrace that are actual MSH format errors (i.e. filters out all internal nom parser errors)

pub fn first_msh_error(&self) -> Option<MshParserErrorKind>

Returns the kind of the first error in the backtrace that is an actual MSH format error kind (i.e. skips internal nom parser errors)

impl<I: Clone> MshParserError<I>

pub fn filtered_backtrace(&self) -> Vec<(I, MshParserErrorKind)>

Returns a backtrace containing only the errors that are actual MSH format errors (i.e. without internal nom parser errors)

Trait Implementations

impl<I: Debug> Debug for MshParserError<I>

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

Formats the value using the given formatter.

impl<'_, I: Debug + HexDisplay + ?Sized> Display for MshParserError<&'_ I>

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

Formats the value using the given formatter.

impl<'_, I: Debug + HexDisplay + ?Sized> Error for MshParserError<&'_ I>

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<I: Debug, E: Into<MshParserError<I>>> From<Err<E>> for MshParserError<I>

Convert a nom::Err to MshParserError

fn from(error: Err<E>) -> Self

Performs the conversion.

impl<I> ParseError<I> for MshParserError<I>

fn from_error_kind(input: I, kind: ErrorKind) -> Self

creates an error from the input position and an [ErrorKind]

fn append(input: I, kind: ErrorKind, other: Self) -> Self

combines an existing error with a new one created from the input position and an [ErrorKind]. This is useful when backtracking through a parse tree, accumulating error context on the way

fn add_context(input: I, ctx: &'static str, other: Self) -> Self

create a new error from an input position, a static string and an existing error. This is used mainly in the [context] combinator, to add user friendly information to errors when backtracking through a parse tree

fn from_char(input: I, char) -> Self

creates an error from an input position and an expected character

fn or(self, other: Self) -> Self

combines two existing error. This function is used to compare errors generated in various branches of [alt]
