Struct Error 

#[non_exhaustive]
pub struct Error {
    pub kind: ErrorKind,
    pub at: Position,
}

An error from a decoder or encoder, with the stream position it was found at.

Errors are Copy: after one, the codec repeats it on every later call until it is reset, so a caller that retries sees exactly the same error. Build one with Error::new.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

kind: ErrorKind

What went wrong.

at: Position

Where it was found.

Implementations

impl Error

pub const fn new(kind: ErrorKind) -> Self

An error of kind at the start of the stream.

pub const fn kind(&self) -> ErrorKind

What went wrong.

pub const fn position(&self) -> Position

Where it was found.

pub const fn is_data_error(&self) -> bool

Whether the bytes of the stream are at fault (ErrorKind::Corrupt or ErrorKind::Truncated), as opposed to the parameters or the memory available. A container that can repair or refetch data treats these as repairable.

pub const fn is_resource_error(&self) -> bool

Whether memory refused the model (ErrorKind::MemoryLimit or ErrorKind::AllocationFailed), as opposed to the data, the parameters or the codec. A container reports these as a resource limit rather than as damage.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Error

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

The text deliberately avoids the words “method”, “unsupported”, “password” and “encrypted”: archive tooling downstream classifies errors by matching them, and a PPMd error is none of those.

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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<Error> for Error

Available on crate feature std only.

Errors as std::io::Errors, for code that drives a codec through Read or Write: a corrupt stream is InvalidData, a truncated one UnexpectedEof, bad parameters InvalidInput, a memory refusal OutOfMemory, and an internal failure Other. The Error stays inside and can be recovered with downcast::<Error>().

fn from(e: Error) -> Self

Converts to this type from the input type.

impl PartialEq for Error

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

Equality operator ==.

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

Inequality operator !=.
