Buffer errors.

Please keep in mind that this enum is non exhaustive; you will not be able to exhaustively pattern-match against it.

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.

CannotCreate

Cannot create buffer.

Overflow

Overflow when setting a value with a specific index.

Contains the index and the size of the buffer.

Fields of Overflow

index: usize

Tried index.

buffer_len: usize

Actuall buffer length.

TooFewValues

Too few values were passed to fill a buffer.

Contains the number of passed value and the size of the buffer.

Fields of TooFewValues

provided_len: usize

Length of the provided data.

buffer_len: usize

Actual buffer length.

TooManyValues

Too many values were passed to fill a buffer.

Contains the number of passed value and the size of the buffer.

Fields of TooManyValues

provided_len: usize

Length of the provided data.

buffer_len: usize

Actual buffer length.

MapFailed

Buffer mapping failed.

Implementations

impl BufferError

pub fn cannot_create() -> Self

pub fn overflow(index: usize, buffer_len: usize) -> Self

Overflow when setting a value with a specific index.

pub fn too_few_values(provided_len: usize, buffer_len: usize) -> Self

Trait Implementations

impl Debug for BufferError

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

Formats the value using the given formatter.

impl Display for BufferError

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

Formats the value using the given formatter.

impl Error for BufferError

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()

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<BufferError> for TessMapError

fn from(e: BufferError) -> Self

Performs the conversion.

impl From<BufferError> for TessError

fn from(e: BufferError) -> Self
