Struct Mapping 

pub struct Mapping {
    pub generated_line: u32,
    pub generated_column: u32,
    pub source_index: Option<u32>,
    pub original_line: Option<u32>,
    pub original_column: Option<u32>,
    pub name_index: Option<u32>,
}

A single mapping entry in a source map.

Each mapping describes how a generated position maps back to an original position in a source file.

Fields

generated_line: u32

Generated line (0-indexed).

generated_column: u32

Generated column (0-indexed).

source_index: Option<u32>

Source file index (if this mapping has a source).

original_line: Option<u32>

Original line (0-indexed, if this mapping has a source).

original_column: Option<u32>

Original column (0-indexed, if this mapping has a source).

name_index: Option<u32>

Name index (if this mapping has a name).

Implementations

impl Mapping

pub fn generated_only(line: u32, column: u32) -> Self

Creates a new mapping with only generated position.

pub fn full( generated_line: u32, generated_column: u32, source_index: u32, original_line: u32, original_column: u32, name_index: Option<u32>, ) -> Self

Creates a new mapping with full information.

pub fn has_source(&self) -> bool

Checks if this mapping has source information.

pub fn has_name(&self) -> bool

Checks if this mapping has a name.

pub fn source_index_or_zero(&self) -> u32

Returns the source index, or 0 if none.

pub fn original_line_or_zero(&self) -> u32

Returns the original line, or 0 if none.

pub fn original_column_or_zero(&self) -> u32

Returns the original column, or 0 if none.

pub fn name_index_or_zero(&self) -> u32

Returns the name index, or 0 if none.

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 Hash for Mapping

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Mapping

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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 PartialOrd for Mapping

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
