Enum LoadError 

pub enum LoadError {
    Library(Error),
    MissingEntryPoint,
}

Error returned when the Vulkan shared library cannot be loaded.

This is distinct from vk::Result, it represents a failure to reach the Vulkan API at all, not a Vulkan API error.

Examples

use vulkan_rust::LoadError;

let err = LoadError::MissingEntryPoint;
assert_eq!(
    err.to_string(),
    "vkGetInstanceProcAddr not found in Vulkan library",
);

Variants

Library(Error)

The Vulkan shared library could not be found or opened.

MissingEntryPoint

vkGetInstanceProcAddr could not be resolved from the library.

Trait Implementations

impl Debug for LoadError

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

Formats the value using the given formatter.

impl Display for LoadError

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

Formats the value using the given formatter.

impl Error for LoadError

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.
