Struct ShiftSettings 

pub struct ShiftSettings {
    pub typographic: bool,
    pub shift: Smart<Em>,
    pub size: Smart<Em>,
    pub kind: ScriptKind,
}

Configuration values for sub- or superscript text.

Fields

typographic: bool

Whether the OpenType feature should be used if possible.

shift: Smart<Em>

The baseline shift of the script, relative to the outer text size.

For superscripts, this is positive. For subscripts, this is negative. A value of Smart::Auto indicates that the value should be obtained from font metrics.

size: Smart<Em>

The size of the script, relative to the outer text size.

A value of Smart::Auto indicates that the value should be obtained from font metrics.

kind: ScriptKind

The kind of script (either a subscript, or a superscript).

This is used to know which OpenType table to use to resolve Smart::Auto values.

Trait Implementations

impl Clone for ShiftSettings

fn clone(&self) -> ShiftSettings

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShiftSettings

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

Formats the value using the given formatter.

impl Hash for ShiftSettings

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 PartialEq for ShiftSettings

fn eq(&self, other: &ShiftSettings) -> 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.
