Variants

Nom(ErrorKind, Option<Box<Self>>)

We encountered a generic nom error while parsing.

Io(Error)

We encountered an error performing I/O to read the trace session.

InvalidUtf8(Utf8Error)

We encountered invalid UTF-8 while parsing.

MissingMagicNumber

We encountered a non-magic-number record at the beginning of the session.

WrongType

We encountered an unexpected type ordinal while parsing.

Fields

expected: u8

observed: u8

context: &'static str

InvalidMagicNumber

We encountered an incorrect magic number while parsing.

Fields

observed: u32

InvalidRef

We encountered an invalid reference, like a zero thread id.

InvalidSize

We encountered an invalid length for a record.

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, __formatter: &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.

impl From<Utf8Error> for ParseError

fn from(source: Utf8Error) -> Self

Converts to this type from the input type.

impl FromExternalError<&[u8], ParseError> for ParseError

fn from_external_error(_input: &[u8], _kind: ErrorKind, e: ParseError) -> Self

Creates a new error from an input position, an [ErrorKind] indicating the wrapping parser, and an external error

impl ParseError<&[u8]> for ParseError

fn from_error_kind(_input: &[u8], kind: ErrorKind) -> Self

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

fn append(_input: &[u8], kind: ErrorKind, prev: 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 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 errors. This function is used to compare errors generated in various branches of alt.
