Trait Implementations

impl<ET: Clone + EngineTypes, S: Clone + MathFontStyleT<ET>> Clone for MathKernel<ET, S>

where ET::Char: Clone,

fn clone(&self) -> MathKernel<ET, S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<ET: Debug + EngineTypes, S: Debug + MathFontStyleT<ET>> Debug for MathKernel<ET, S>

where ET::Char: Debug,

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

Formats the value using the given formatter.

impl<ET: EngineTypes, S: MathFontStyleT<ET>> Default for MathKernel<ET, S>

fn default() -> MathKernel<ET, S>

Returns the “default value” for a type.

impl<ET: EngineTypes> NodeTrait<ET> for MathKernel<ET, MathFontStyle<ET>>

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

Produces a human-readable string; since nodes are deeply nested, takes an additional indent value to indent the string

fn height(&self) -> ET::Dim

Returns the height of the node.

fn width(&self) -> ET::Dim

Returns the width of the node.

fn depth(&self) -> ET::Dim

Returns the depth of the node.

fn nodetype(&self) -> NodeType

Returns the type of the node, as returned by \lastnodetype.

fn display(&self) -> DisplayNode<'_, ET, Self>

Returns a helper struct that implements Display and uses Self::display_fmt to yield a human-readable string.

fn opaque(&self) -> bool

Whether this node is “opaque”; meaning: When considering a list of nodes (e.g. in \unskip or \lastbox, this node should not be considered. Useful for annotation/marker nodes some engine wants to insert, without impacting algorithms that inspect e.g. the last node of the current list.

fn sourceref(&self) -> Option<(&SourceRef<ET>, &SourceRef<ET>)>
