Enum Scalar 

#[non_exhaustive]
pub enum Scalar {
    Dxgi,
    D3d9,
    Wined3d,
    OpenGl,
    DpiAware,
    LargeAddressAware,
    Gcmouse,
    ForceNx,
    MetalHud,
}

A setting that holds one value (see KeyKind::Scalar), or is reset with default (see Setting::Reset).

Each variant is the setting of its Key, whose doc says what it does and what a process gets without it.

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.

Dxgi

Key::Dxgi: the implementation of D3D10 to D3D12. Unset: wined3d.

D3d9

Key::D3d9: the D3D9 implementation. Unset: wined3d.

Wined3d

Key::Wined3d: the renderer of wined3d. Unset: what WINE_D3D_CONFIG or the registry says, otherwise OpenGL.

OpenGl

Key::OpenGl: the Mac driver’s OpenGL. Unset: Apple’s.

DpiAware

Key::DpiAware: DPI awareness. Unset: the registry and the manifest decide.

LargeAddressAware

Key::LargeAddressAware: 4 GB for a 32-bit process. Unset: the executable’s flag decides.

Gcmouse

Key::Gcmouse: raw mouse movement from GameController. Unset: from the cursor.

ForceNx

Key::ForceNx: no-execute kept on in a 32-bit process. Unset: Wine’s behaviour.

MetalHud

Key::MetalHud: the Metal performance HUD. Unset: the inherited variables decide.

Implementations

impl Scalar

pub const ALL: &'static [Self]

Every scalar setting, in the order a record writes them.

pub const fn key(self) -> Key

The key of this setting.

pub const fn as_str(self) -> &'static str

The key of this setting as the wire writes it.

pub const fn value_kind(self) -> ValueKind

The kind of value this setting holds.

pub const fn upstream(self) -> &'static str

What upstream Wine does for this setting when no rule sets it (see Key::upstream).

pub fn parse_value(self, text: &str) -> Result<ScalarValue, FieldError>

Read text as a value of this setting, ASCII-case-insensitively. default is not a value: it resets the setting (see Setting::Reset).

Errors

FieldError::BadValue when the setting does not take text. Its expected is Key::values, default included, since it lists what a field of the key takes.

Trait Implementations

impl Clone for Scalar

fn clone(&self) -> Scalar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Scalar

impl Debug for Scalar

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

Formats the value using the given formatter.

impl Display for Scalar

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

Formats the value using the given formatter.

impl Eq for Scalar

impl Hash for Scalar

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 Scalar

fn cmp(&self, other: &Scalar) -> 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 Scalar

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for Scalar

fn partial_cmp(&self, other: &Scalar) -> 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.
