Struct SettingsSchema 

pub struct SettingsSchema { /* private fields */ }

schema_source, schema_id, FALSE);

if (schema == NULL) { … disable the plugin or abort, etc … }

return g_settings_new_full (schema, NULL, NULL); }

The code above shows how hooks should be added to the code that
initialises (or enables) the plugin to create the schema source and
how an API can be added to the plugin system to provide a convenient
way for the plugin to access its settings, using the schemas that it
ships.

From the standpoint of the plugin, it would need to ensure that it
ships a gschemas.compiled file as part of itself, and then simply do
the following:

```c
{
  GSettings *settings;
  gint some_value;

  settings = plugin_get_settings (self, NULL);
  some_value = g_settings_get_int (settings, "some-value");
  …
}
```text

It's also possible that the plugin system expects the schema source
files (ie: `.gschema.xml` files) instead of a `gschemas.compiled` file.
In that case, the plugin loading system must compile the schemas for
itself before attempting to create the settings source.

GLib type: Shared boxed type with reference counted clone semantics.

Implementations

impl SettingsSchema

pub fn as_ptr(&self) -> *mut GSettingsSchema

Return the inner pointer to the underlying C value.

pub unsafe fn from_glib_ptr_borrow(ptr: &*mut GSettingsSchema) -> &Self

Borrows the underlying C value.

impl SettingsSchema

pub fn id(&self) -> GString

Get the ID of @self.

Returns

the ID

pub fn key(&self, name: &str) -> SettingsSchemaKey

Gets the key named @name from @self.

It is a programmer error to request a key that does not exist. See g_settings_schema_list_keys().

name

the name of a key

Returns

the #GSettingsSchemaKey for @name

pub fn path(&self) -> Option<GString>

Gets the path associated with @self, or None.

Schemas may be single-instance or relocatable. Single-instance schemas correspond to exactly one set of keys in the backend database: those located at the path returned by this function.

Relocatable schemas can be referenced by other schemas and can therefore describe multiple sets of keys at different locations. For relocatable schemas, this function will return None.

Returns

the path of the schema, or None

pub fn has_key(&self, name: &str) -> bool

Checks if @self has a key named @name.

name

the name of a key

Returns

true if such a key exists

pub fn list_children(&self) -> Vec<GString>

Gets the list of children in @self.

You should free the return value with g_strfreev() when you are done with it.

Returns

a list of the children on @settings, in no defined order

pub fn list_keys(&self) -> Vec<GString>

Introspects the list of keys on @self.

You should probably not be calling this function from “normal” code (since you should already know what keys are in your schema). This function is intended for introspection reasons.

Returns

a list of the keys on @self, in no defined order

Trait Implementations

impl Clone for SettingsSchema

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 SettingsSchema

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

Formats the value using the given formatter.

impl Eq for SettingsSchema

impl From<SettingsSchema> for Value

fn from(s: SettingsSchema) -> Self

Converts to this type from the input type.

impl HasParamSpec for SettingsSchema

type ParamSpec = ParamSpecBoxed

type SetValue = SettingsSchema

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(&str) -> ParamSpecBoxedBuilder<'_, SettingsSchema>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for SettingsSchema

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 SettingsSchema

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

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for SettingsSchema

fn partial_cmp(&self, other: &SettingsSchema) -> 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 SettingsSchema

fn static_type() -> Type

Returns the type identifier of Self.
