}

An error that may be returned from a GLFW operation.

These correspond 1:1 with

Variants

NotInitialized

An error returned when GLFW has not been initialized.

NoCurrentContext

An error returned when the current context is incorrect.

InvalidEnum

An error returned when an enumerated value is out of the range of valid inputs.

InvalidValue

An error returned when a value is outsode fh te range of valid inputs.

OutOfMemory

An error returned if GLFW runs out of memory.

ApiUnavailable

An error returned if an API has been disabled or is unavailable

VersionUnavailable

An error returned if an API is available, but a specific version is unavailable (such as the OpenGL version)

PlatformError

A generic platform-specific error has occurred.

FormatUnavailable

A specific format is unavailable.

NoWindowContext

An error that occurs when no window context is available.

Unknown(c_int)

An error outside of this enumeration has occurred. If this shows up, it means GLFW either didn’t document an error-code, or it has added a new error code in an update.

Implementations

impl Error

pub fn from_glfw_status(code: c_int) -> Self

Constructs this Error from a GLFW status value.

Parameters

• code - the GLFW status code

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.
