Enum SourceRole 

#[non_exhaustive]
pub enum SourceRole {
    Primary,
    EnclosingConstruct,
    MacroExpansion,
    ResourceRequest,
    Package,
    FontDefinition,
    Resource,
}

How a source range contributed to a node.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Primary

The primary user visible expression source.

EnclosingConstruct

Enclosing construct or macro invocation range; entries are emitted innermost first.

MacroExpansion

Macro expansion whose expansion produced this node.

ResourceRequest

User source declaration that requested a resource, such as \input or \usepackage.

Package

Package file that defined a macro or environment used here.

FontDefinition

TeX font definition source such as .fd.

Resource

Generic resource file referenced during typesetting.

Trait Implementations

impl Clone for SourceRole

fn clone(&self) -> SourceRole

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SourceRole

impl Debug for SourceRole

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

Formats the value using the given formatter.

impl Eq for SourceRole

impl PartialEq for SourceRole

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