Enum PpmError 

pub enum PpmError {
    IoError(Error),
    CorruptData,
    InvalidState,
    ModelError(&'static str),
}

The set of errors that can occur during PPM encoding or decoding.

Variants

IoError(Error)

Errors from any underlying I/O operations (file, stream, etc.).

CorruptData

The input data was unexpectedly corrupt (e.g., decoder sees an impossible symbol).

InvalidState

The decoder was put into an invalid state (should not happen in normal use).

ModelError(&'static str)

Errors in the PPM model itself (e.g., invalid parameters).

Trait Implementations

impl Debug for PpmError

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

Formats the value using the given formatter.

impl Display for PpmError

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

Formats the value using the given formatter.

impl Error for PpmError

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 PpmError

fn from(source: Error) -> Self

Converts to this type from the input type.
