Enum StcError 

pub enum StcError {
    LengthMismatch {
        pixels: usize,
        costs: usize,
    },
    PayloadExceedsCapacity {
        payload_bits: usize,
        capacity_bits: usize,
    },
    InvalidCostMap,
    EncodingError(String),
    DecodingError(String),
}

Every way the Syndrome-Trellis Codes layer can refuse to run.

Variants

LengthMismatch

The cover vector and the cost vector describe different position counts.

Fields

pixels: usize

Number of cover positions supplied.

costs: usize

Number of costs supplied.

PayloadExceedsCapacity

The payload asks for more bits than max_bpp allows over this cover.

Fields

payload_bits: usize

Bits the payload needs.

capacity_bits: usize

Bits the cover may carry under the max_bpp hard limit.

InvalidCostMap

A cost was negative, infinite or not a number.

EncodingError(String)

The trellis could not be built or could not be solved.

DecodingError(String)

The syndrome could not be computed for the parameters given.

Trait Implementations

impl Debug for StcError

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

Formats the value using the given formatter.

impl Display for StcError

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

Formats the value using the given formatter.

impl Error for StcError

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<StcError> for PipelineError

fn from(err: StcError) -> Self

Converts to this type from the input type.
