    },
}

Possible error that might occur while dealing with TessView objects.

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.

IncorrectViewWindow

The view has incorrect size.

data.

Fields of IncorrectViewWindow

capacity: usize

Capacity of data in the Tess.

start: usize

Requested start.

nb: usize

Requested number.

Trait Implementations

impl Debug for TessViewError

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

Formats the value using the given formatter.

impl Display for TessViewError

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

Formats the value using the given formatter.

impl Error for TessViewError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
