Implementations

impl TreeExpander

pub fn new() -> TreeExpander

pub fn builder() -> TreeExpanderBuilder

Creates a new builder-pattern struct instance to construct TreeExpander objects.

This method returns an instance of TreeExpanderBuilder which can be used to create TreeExpander objects.

Performs copy-assignment from source.

impl Debug for TreeExpander

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

Formats the value using the given formatter.

impl Default for TreeExpander

fn default() -> Self

Returns the “default value” for a type.

impl Display for TreeExpander

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

Formats the value using the given formatter.

impl Hash for TreeExpander

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

Feeds this value into the given Hasher.

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

impl Ord for TreeExpander

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

impl ParentClassIs for TreeExpander

type Parent = Widget

impl<OT: ObjectType> PartialEq<OT> for TreeExpander

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

This method tests for self and other values to be equal, and is used by ==.

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

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

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl StaticType for TreeExpander

fn static_type() -> Type

Returns the type identifier of Self.
