Enum GeneratorError 

#[non_exhaustive]
pub enum GeneratorError {
    TooLargeInput,
    TooSmallInput,
    BucketsAreHalfEmpty,
    BucketsAreThreeQuarterEmpty,
}

An error type representing an error while generating a fuzzy hash.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

TooLargeInput

The input data is too large to process.

TooSmallInput

The input data is too small to process.

Whether the input data is too small is normally determined by the value of DataLengthProcessingMode.

If we prefer compatibility with the original TLSH implementation, we cannot generate a fuzzy hash from the data smaller than 50 bytes.

BucketsAreHalfEmpty

Too many buckets (roughly half or more) are empty.

This error indicates the input data is either too small or too repetitive so that enough number of buckets cannot be filled (i.e. even if we force to output a fuzzy hash, the result might be statistically unreliable).

BucketsAreThreeQuarterEmpty

Too many buckets (roughly 3/4 or more) are empty.

This is similar to BucketsAreHalfEmpty but indicates more extreme statistic distribution so that computing a Q ratio will result in a division by zero.

Implementations

impl GeneratorError

pub fn category(&self) -> GeneratorErrorCategory

Retrieves the category of the generator error.

Trait Implementations

impl Clone for GeneratorError

fn clone(&self) -> GeneratorError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GeneratorError

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

Formats the value using the given formatter.

impl Display for GeneratorError

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

Formats the value using the given formatter.

impl Error for GeneratorError

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<GeneratorError> for GeneratorOrIOError

Available on crate features easy-functions and std only.

fn from(value: GeneratorError) -> Self

Converts to this type from the input type.

impl PartialEq for GeneratorError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
