Struct Fragment 

pub struct Fragment {
    pub surface: Surface,
    pub nodes: Vec<LayoutNode>,
    pub source_map: SourceMap,
    pub metadata: FragmentMetadata,
}

A complete renderer neutral layout result for one TeX/LaTeX fragment.

Fields

surface: Surface

Fragment coordinate surface dimensions.

nodes: Vec<LayoutNode>

All layout nodes in this fragment.

source_map: SourceMap

Source map relating nodes back to input positions.

metadata: FragmentMetadata

Metadata about the engine and format that produced this fragment.

Implementations

impl Fragment

pub fn node(&self, node: NodeId) -> Option<&LayoutNode>

Returns the layout node with the given identifier, if present.

pub fn source_entries_for_node( &self, node: NodeId, ) -> impl Iterator<Item = &SourceMapEntry>

Iterates all source map entries for the given node.

pub fn source_origins_for_node( &self, node: NodeId, ) -> impl Iterator<Item = SourceOrigin<'_>>

Iterates resolved source origins for the given node.

pub fn source_origin_for_entry( &self, entry: &SourceMapEntry, ) -> Option<SourceOrigin<'_>>

Resolves a source map entry to its origin metadata.

pub fn primary_source_for_node(&self, node: NodeId) -> Option<SourceRange>

Returns the primary source range for the given node, if any.

pub fn glyph_source_range( &self, node: NodeId, glyph_index: usize, ) -> Option<SourceRange>

Resolves the glyph cluster byte span to a SourceRange using the node’s primary source.

pub fn glyph_source_origin( &self, node: NodeId, glyph_index: usize, ) -> Option<SourceOrigin<'_>>

Resolves a glyph’s source cluster to a full SourceOrigin.

Trait Implementations

impl Clone for Fragment

fn clone(&self) -> Fragment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Fragment

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

Formats the value using the given formatter.

impl Default for Fragment

fn default() -> Fragment

Returns the “default value” for a type.

impl PartialEq for Fragment

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