Enum MergeError 

pub enum MergeError {
    WrongLength {
        expected: usize,
        got: usize,
    },
    Overlap {
        first_sample: u32,
        done: u32,
    },
}

Why Merger::add refused a chunk. A refused chunk contributes nothing, so the count always matches the buffer.

Variants

WrongLength

The chunk’s buffer is not width * height long.

Fields

expected: usize

The merger’s pixel count.

got: usize

The chunk’s buffer length.

Overlap

The chunk overlaps samples already merged or parked: a disjointness violation.

Fields

first_sample: u32

The refused chunk’s first sample.

done: u32

The refused chunk’s traced sample count.

Trait Implementations

impl Clone for MergeError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MergeError

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

Formats the value using the given formatter.

impl Display for MergeError

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

Formats the value using the given formatter.

impl Eq for MergeError

impl Error for MergeError

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 MergeError

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

Equality operator ==.

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

Inequality operator !=.
