Enum SystemError

#[non_exhaustive]
pub enum SystemError {
    CoglSystemErrorUnsupported,
    CoglSystemErrorNoMemory,
}

Error enumeration for Cogl

The SystemError::CoglSystemErrorUnsupported error can be thrown for a variety of reasons. For example:

<itemizedlist> <listitem>``<para>You’ve tried to use a feature that is not advertised by cogl_has_feature. This could happen if you create a 2d texture with a non-power-of-two size when FeatureID::OglFeatureIdTextureNpot is not advertised.</para>``</listitem> <listitem>``<para>The GPU can not handle the configuration you have requested. An example might be if you try to use too many texture layers in a single Pipeline``</para>``</listitem> <listitem>``<para>The driver does not support some configuration.</para>``</listiem> </itemizedlist>

Currently this is only used by Cogl API marked as experimental so this enum should also be considered experimental.

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.

CoglSystemErrorUnsupported

You tried to use a feature or configuration not currently available.

CoglSystemErrorNoMemory

You tried to allocate a resource such as a texture and there wasn’t enough memory.

Trait Implementations

fn clone(&self) -> SystemError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SystemError

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

Formats the value using the given formatter.

impl Display for SystemError

Formats the value using the given formatter.

impl<'a> FromValue<'a> for SystemError

unsafe fn from_value(value: &Value) -> Self

Safety

impl<'a> FromValueOptional<'a> for SystemError

unsafe fn from_value_optional(value: &Value) -> Option<Self>

Safety

impl Hash for SystemError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SystemError

fn cmp(&self, other: &SystemError) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SystemError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for SystemError

fn partial_cmp(&self, other: &SystemError) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl SetValue for SystemError

unsafe fn set_value(value: &mut Value, this: &Self)

Safety

impl StaticType for SystemError

fn static_type() -> Type

Returns the type identifier of Self.

impl Copy for SystemError

impl Eq for SystemError
