Struct Mapping

pub struct Mapping {
    pub generated_line: u32,
    pub generated_column: u32,
    pub last_generated_column: Option<u32>,
    pub original: Option<OriginalLocation>,
}

A single bidirectional mapping.

Always contains generated location information.

Might contain original location information, and if so, might also have an associated name.

Fields

generated_line: u32

The generated line.

generated_column: u32

The generated column.

last_generated_column: Option<u32>

The end column of this mapping’s generated location span.

Before Mappings::computed_column_spans has been called, this is always None. After Mappings::computed_column_spans has been called, it either contains Some column at which the generated location ends (exclusive), or it contains None if it spans until the end of the generated line.

original: Option<OriginalLocation>

The original location information, if any.

Trait Implementations

impl Clone for Mapping

fn clone(&self) -> Mapping

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ComparatorFunction<Mapping> for ByGeneratedTail

fn compare(a: &Mapping, b: &Mapping) -> Ordering

Compare the given values.

impl ComparatorFunction<Mapping> for ByOriginalLocation

fn compare(a: &Mapping, b: &Mapping) -> Ordering

Compare the given values.

impl ComparatorFunction<Mapping> for ByOriginalLocationSameSource

fn compare(a: &Mapping, b: &Mapping) -> Ordering

Compare the given values.

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 PartialEq for Mapping

fn eq(&self, other: &Mapping) -> 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 Eq for Mapping
