Enum ProducerError 

#[non_exhaustive]
pub enum ProducerError {
    Allocate(String),
    Unsupported,
}

Why a producer could not hand over a buffer.

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.

Allocate(String)

The producer could not allocate what was asked for.

Unsupported

The producer can make none of the layouts it was allowed.

Refused rather than allocated outside the set: a buffer in a layout no plane takes fails at the atomic commit, naming the framebuffer rather than the layout that made it unscannable (drm-cxx f5bed8f).

Trait Implementations

impl Debug for ProducerError

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

Formats the value using the given formatter.

impl Display for ProducerError

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

Formats the value using the given formatter.

impl Error for ProducerError

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>)
