Struct CTParagraphStyleSpecifier 

#[repr(transparent)]
pub struct CTParagraphStyleSpecifier(pub u32);

Available on crate feature CTParagraphStyle only.

These constants are used to query and modify the CTParagraphStyle object.

Each specifier has a type and a default value associated with it. The type must always be observed when setting or fetching the value from the CTParagraphStyle object. In addition, some specifiers affect the behavior of both the framesetter and the typesetter, and others only affect the behavior of the framesetter; this is also noted below.

The text alignment. Natural text alignment is realized as left or right alignment, depending on the line sweep direction of the first script contained in the paragraph.

Type: CTTextAlignment Default: kCTTextAlignmentNatural Application: CTFramesetter

The distance in points from the leading margin of a frame to the beginning of the paragraph’s first line. This value is always nonnegative.

Type: CGFloat Default: 0.0 Application: CTFramesetter

The distance in points from the leading margin of a text container to the beginning of lines other than the first. This value is always nonnegative.

Type: CGFloat Default: 0.0 Application: CTFramesetter

The distance in points from the margin of a frame to the end of lines. If positive, this value is the distance from the leading margin (for example, the left margin in left-to-right text). If 0 or negative, it’s the distance from the trailing margin.

Type: CGFloat Default: 0.0 Application: CTFramesetter

The CTTextTab objects, sorted by location, that define the tab stops for the paragraph style.

Type: CFArray of CTTextTabRef Default: 12 left-aligned tabs, spaced by 28.0 points Application: CTFramesetter, CTTypesetter

The document-wide default tab interval. Tabs after the last specified by kCTParagraphStyleSpecifierTabStops are placed at integer multiples of this distance (if positive).

Type: CGFloat Default: 0.0 Application: CTFramesetter, CTTypesetter

The mode that should be used to break lines when laying out the paragraph’s text.

Type: CTLineBreakMode Default: kCTLineBreakByWordWrapping Application: CTFramesetter

The line height multiple. The natural line height of the receiver is multiplied by this factor (if positive) before being constrained by minimum and maximum line height.

Type: CGFloat Default: 0.0 Application: CTFramesetter

The maximum height that any line in the frame will occupy, regardless of the font size or size of any attached graphic. Glyphs and graphics exceeding this height will overlap neighboring lines. A maximum height of 0 implies no line height limit. This value is always nonnegative.

Type: CGFloat Default: 0.0 Application: CTFramesetter

The minimum height that any line in the frame will occupy, regardless of the font size or size of any attached graphic. This value is always nonnegative.

Type: CGFloat Default: 0.0 Application: CTFramesetter

Deprecated. Use kCTParagraphStyleSpecifierMaximumLineSpacing, kCTParagraphStyleSpecifierMinimumLineSpacing, and kCTParagraphStyleSpecifierLineSpacingAdjustment to control space between lines.

The space added at the end of the paragraph to separate it from the following paragraph. This value is always nonnegative and is determined by adding the previous paragraph’s kCTParagraphStyleSpecifierParagraphSpacing setting and the current paragraph’s kCTParagraphStyleSpecifierParagraphSpacingBefore setting.

Type: CGFloat Default: 0.0 Application: CTFramesetter

The distance between the paragraph’s top and the beginning of its text content.

Type: CGFloat Default: 0.0 Application: CTFramesetter

The base writing direction of the lines.

Type: CTWritingDirection Default: kCTWritingDirectionNatural Application: CTFramesetter, CTTypesetter

The maximum space in points between lines within the paragraph (commonly known as leading).

Type: CGFloat Default: some large number. Application: CTFramesetter

The minimum space in points between lines within the paragraph (commonly known as leading).

Type: CGFloat Default: 0.0 Application: CTFramesetter

The space in points added between lines within the paragraph (commonly known as leading).

Type: CGFloat Default: 0.0 Application: CTFramesetter

The options controlling the alignment of the line edges with the leading and trailing margins.

Type: CTLineBoundsOptions Default: 0 (no options) Application: CTTypesetter

Trait Implementations

impl Clone for CTParagraphStyleSpecifier

fn clone(&self) -> CTParagraphStyleSpecifier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CTParagraphStyleSpecifier

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

Formats the value using the given formatter.

impl Encode for CTParagraphStyleSpecifier

Available on crate feature objc2 only.

const ENCODING: Encoding = u32::ENCODING

The Objective-C type-encoding for this type.

impl Hash for CTParagraphStyleSpecifier

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 CTParagraphStyleSpecifier

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