Enum ConstTransformError 

#[non_exhaustive]
pub enum ConstTransformError {
    LengthOverflow,
    Input(InputError),
    OutputLengthMismatch {
        required: usize,
        actual: usize,
    },
}

Error returned by an exact const transform.

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.

LengthOverflow

The exact output length cannot be represented by usize.

Input(InputError)

The encoded input is malformed under the selected codec settings.

OutputLengthMismatch

The output array length is not the exact result length.

Fields

required: usize

Exact required output bytes.

actual: usize

Compile-time output array length supplied by the caller.

impl Eq for ConstTransformError

impl Error for ConstTransformError

Available on crate feature std only.

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
