pub fn blurb(&self) -> Option<&str>

Get the short description of a ParamSpec.

Returns

the short description of self. Get the short description of a ParamSpec.

Returns

the short description of self.

pub fn default_value(&self) -> &Value

Gets the default value of self as a pointer to a Value.

The Value will remain valid for the life of self.

Returns

a pointer to a Value which must not be modified Gets the default value of self as a pointer to a Value.

The Value will remain valid for the life of self.

Returns

a pointer to a Value which must not be modified

pub fn name<'a>(&self) -> &'a str

Get the name of a ParamSpec.

The name is always an “interned” string (as per g_intern_string()). This allows for pointer-value comparisons.

Returns

the name of self. Get the name of a ParamSpec.

The name is always an “interned” string (as per g_intern_string()). This allows for pointer-value comparisons.

Returns

the name of self.

pub fn name_quark(&self) -> Quark

Gets the GQuark for the name.

Returns

the GQuark for self->name. Gets the GQuark for the name.

Returns

the GQuark for self->name.

pub fn nick(&self) -> &str

Returns the nickname of this ParamSpec.

If this ParamSpec does not have a nickname, the nickname of its redirect target is returned if it has one. Otherwise, self.name() is returned. Get the nickname of a ParamSpec.

Returns

the nickname of self. Get the nickname of a ParamSpec.

Returns

the nickname of self.

pub fn redirect_target(&self) -> Option<ParamSpec>

contains references to other environment variables, they are expanded.

variable

the environment variable to get

Returns

the value of the environment variable, or None if the environment variable is not found. The returned string may be overwritten by the next call to g_getenv(), g_setenv() or g_unsetenv(). If the paramspec redirects operations to another paramspec, returns that paramspec. Redirect is used typically for providing a new implementation of a property in a derived type while preserving all the properties from the parent type. Redirection is established by creating a property of type ParamSpecOverride. See g_object_class_override_property() for an example of the use of this capability.

Returns

paramspec to which requests on this paramspec should be redirected, or None if none.

Trait Implementations

impl AsRef<ParamSpec> for ParamSpecInt64

fn as_ref(&self) -> &ParamSpec

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ParamSpecInt64

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the reference. Dropping the reference will decrement it again.

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

Performs copy-assignment from source.

impl Debug for ParamSpecInt64

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

Formats the value using the given formatter.

impl Deref for ParamSpecInt64

type Target = ParamSpec

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Hash for ParamSpecInt64

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 ParamSpecInt64

fn cmp(&self, other: &ParamSpecInt64) -> 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 ParamSpecInt64

fn eq(&self, other: &ParamSpecInt64) -> 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 ParamSpecInt64

fn partial_cmp(&self, other: &ParamSpecInt64) -> 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 StaticType for ParamSpecInt64

fn static_type() -> Type

Returns the type identifier of Self.
