Implementations

impl Error

pub const fn invalid_value(tag: Tag, msg: String) -> Error

Build an error from the provided invalid value

pub const fn unexpected_class(expected: Option<Class>, actual: Class) -> Error

Build an error from the provided unexpected class

pub const fn unexpected_tag(expected: Option<Tag>, actual: Tag) -> Error

Build an error from the provided unexpected tag

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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, formatter: &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()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Err<Error>> for Error

fn from(e: Err<Error>) -> Error

Converts to this type from the input type.

impl From<FromUtf16Error> for Error

fn from(FromUtf16Error) -> Error

Converts to this type from the input type.

impl From<FromUtf8Error> for Error

fn from(FromUtf8Error) -> Error

Converts to this type from the input type.

impl From<Utf8Error> for Error

fn from(Utf8Error) -> Error

Converts to this type from the input type.

impl<'a> FromBer<'a, Error> for Header<'a>

fn from_ber(bytes: &'a [u8]) -> Result<(&'a [u8], Header<'a>), Err<Error>>

Attempt to parse input bytes into a BER object

impl<'a> FromDer<'a, Error> for Header<'a>

fn from_der(bytes: &'a [u8]) -> Result<(&'a [u8], Header<'a>), Err<Error>>

Attempt to parse input bytes into a DER object (enforcing constraints)

impl<I, E> FromExternalError<I, E> for Error

fn from_external_error(_input: I, kind: ErrorKind, _e: E) -> Error

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

impl<'a> ParseError<&'a [u8]> for Error

fn from_error_kind(_input: &'a [u8], kind: ErrorKind) -> Error

Creates an error from the input position and an ErrorKind

fn append(_input: &'a [u8], kind: ErrorKind, _other: Error) -> Error

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.

impl PartialEq<Error> for Error

fn eq(&self, other: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Error) -> bool

This method tests for !=.

impl StructuralPartialEq for Error
