Struct Mapping 

pub struct Mapping {
    pub to_internal: Vec<Option<Symbol>>,
    pub to_external: Vec<Symbol>,
}

Contains maps for translation between internal and external symbols.

Fields

to_internal: Vec<Option<Symbol>>

An array of internal symbols, indexed by external symbol ID.

to_external: Vec<Symbol>

An array of external symbols, indexed by internal symbol ID.

Implementations

impl Mapping

pub fn new(num_external: usize) -> Self

Creates an empty Mapping. It has zero internal symbols, and space for the given number of external symbols.

pub fn translate(&mut self, other: &Self)

Translates symbols in this map using another symbol map. This map becomes a combination of both mappings.

Trait Implementations

impl Clone for Mapping

fn clone(&self) -> Mapping

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mapping

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

Formats the value using the given formatter.

impl Default for Mapping

fn default() -> Mapping

Returns the “default value” for a type.

impl Deserialize for Mapping

fn begin(__out: &mut Option<Self>) -> &mut dyn Visitor

The only correct implementation of this method is:

impl Serialize for Mapping

fn begin(&self) -> Fragment<'_>
