Enum PresentationError 

pub enum PresentationError {
    NotConfigured,
    SizeMismatch {
        expected_width: u32,
        expected_height: u32,
        actual_width: u32,
        actual_height: u32,
    },
    EmptyBuffer,
    ZeroDimension,
    Softbuffer(String),
}

Error returned by SoftbufferPresenter operations.

Examples

use martensite_render::PresentationError;

// Each variant describes a distinct presentation failure mode.
let err = PresentationError::NotConfigured;
assert_eq!(format!("{err}"), "surface has not been configured");

let err = PresentationError::EmptyBuffer;
assert_eq!(format!("{err}"), "pixel buffer is empty");

let err = PresentationError::ZeroDimension;
assert_eq!(format!("{err}"), "surface width or height is zero");

Variants

NotConfigured

The surface has not been configured yet.

SizeMismatch

The provided buffer size does not match the configured surface size.

Fields

expected_width: u32

Expected width in pixels.

expected_height: u32

Expected height in pixels.

actual_width: u32

Actual buffer width in pixels.

actual_height: u32

Actual buffer height in pixels.

EmptyBuffer

The pixel buffer is empty (zero length).

ZeroDimension

The surface width or height is zero.

Softbuffer(String)

The underlying softbuffer operation failed.

Trait Implementations

impl Debug for PresentationError

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

Formats the value using the given formatter.

impl Display for PresentationError

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

Formats the value using the given formatter.

impl Error for PresentationError

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.
