Struct Dct97GridError 

pub struct Dct97GridError { /* private fields */ }

Error returned when a DCT block grid cannot cover the requested component.

Implementations

pub const fn block_count(self) -> usize

Number of supplied 8x8 DCT blocks.

pub const fn block_cols(self) -> usize

Declared block columns.

pub const fn block_rows(self) -> usize

Declared block rows.

Trait Implementations

impl Clone for DctGridError

fn clone(&self) -> DctGridError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DctGridError

impl Debug for DctGridError

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

Formats the value using the given formatter.

impl Display for DctGridError

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

Formats the value using the given formatter.

impl Eq for DctGridError

impl Error for DctGridError

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 PartialEq for DctGridError

fn eq(&self, other: &DctGridError) -> 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.
