Struct core::Glue

pub struct Glue {
    pub width: Scaled,
    pub stretch: Scaled,
    pub stretch_order: GlueOrder,
    pub shrink: Scaled,
    pub shrink_order: GlueOrder,
}

Glue.

In Knuth’s TeX this struct is not passed around directly; instead Knuth essentially uses std::rc::Rc<Glue>. This optimization is based on the fact that very few distinct glue values appear in a document, and that the pointer takes up less space than the struct. We might consider performing such an optimization.

Described in TeX.2021.150.

Trait Implementations

impl Clone for Glue

fn clone(&self) -> Glue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Glue

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

Formats the value using the given formatter.

impl Default for Glue

fn default() -> Glue

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Glue

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Glue

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

Formats the value using the given formatter.

impl Mul<i32> for Glue

type Output = Glue

The resulting type after applying the * operator.

fn mul(self, rhs: i32) -> Self::Output

Performs the * operation.

impl PartialEq for Glue

fn eq(&self, other: &Glue) -> 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 Serialize for Glue

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Glue

impl Eq for Glue

impl StructuralPartialEq for Glue
