Struct AttrIterator

pub struct AttrIterator<'list> { /* private fields */ }

A AttrIterator is used to iterate through a AttrList.

A new iterator is created with AttrList::iterator(). Once the iterator is created, it can be advanced through the style changes in the text using next_style_change(). At each style change, the range of the current style segment and the attributes currently in effect can be queried.

Implementations

impl<'list> AttrIterator<'list>

pub fn get(&self, type_: AttrType) -> Option<Attribute>

pub fn attrs(&self) -> SList<Attribute>

pub fn next_style_change(&mut self) -> bool

pub fn range(&self) -> (i32, i32)

pub fn font(&self) -> (FontDescription, Option<Language>, SList<Attribute>)

Trait Implementations

impl<'list> Clone for AttrIterator<'list>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'list> Debug for AttrIterator<'list>

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

Formats the value using the given formatter.

impl<'list> Drop for AttrIterator<'list>

fn drop(&mut self)

Executes the destructor for this type.

impl<'list> Hash for AttrIterator<'list>

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<'list> IntoIterator for AttrIterator<'list>

type Item = SList<Attribute>

The type of the elements being iterated over.

type IntoIter = AttrIntoIter<'list>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'list> Ord for AttrIterator<'list>

fn cmp(&self, other: &AttrIterator<'list>) -> 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<'list> PartialEq for AttrIterator<'list>

fn eq(&self, other: &AttrIterator<'list>) -> 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<'list> PartialOrd for AttrIterator<'list>

fn partial_cmp(&self, other: &AttrIterator<'list>) -> 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<'list> StaticType for AttrIterator<'list>

Available on crate feature v1_44 only.

fn static_type() -> Type

Returns the type identifier of Self.
