}

Available on crate features __ecma and __utils only.

A single source in the SourceMap.

Fields

name: Arc<FileName>

The name of the file that the source came from. Source that doesn’t originate from files has names between angle brackets by convention, e.g. <anon>

name_was_remapped: bool

True if the name field above has been modified by --remap-path-prefix

unmapped_path: Option<Arc<FileName>>

The unmapped path of the file that the source came from. Set to None if the SourceFile was imported from an external crate.

crate_of_origin: u32

Indicates which crate this SourceFile was imported from.

src: Arc<String>

The complete source code

src_hash: u128

The source code’s hash

start_pos: BytePos

The start position of this source in the SourceMap

end_pos: BytePos

The end position of this source in the SourceMap

lines: Vec<BytePos>

Locations of lines beginnings in the source code

multibyte_chars: Vec<MultiByteChar>

Locations of multi-byte characters in the source code

non_narrow_chars: Vec<NonNarrowChar>

Width of characters that are not narrow in the source code

name_hash: u128

A hash of the filename, used for speeding up the incr. comp. hashing.

Implementations

impl SourceFile

pub fn new( name: Arc<FileName>, name_was_remapped: bool, unmapped_path: Arc<FileName>, src: String, start_pos: BytePos, ) -> SourceFile

pub fn new_from( name: Arc<FileName>, name_was_remapped: bool, unmapped_path: Arc<FileName>, src: Arc<String>, start_pos: BytePos, ) -> SourceFile

src should not have UTF8 BOM

pub fn line_begin_pos(&self, pos: BytePos) -> BytePos

Return the BytePos of the beginning of the current line.

pub fn get_line(&self, line_number: usize) -> Option<Cow<'_, str>>

Get a line from the list of pre-computed line-beginnings. The line number here is 0-based.

pub fn is_real_file(&self) -> bool

pub fn byte_length(&self) -> u32

pub fn count_lines(&self) -> usize

pub fn lookup_line(&self, pos: BytePos) -> Option<usize>

Find the line containing the given position. The return value is the index into the lines array of this SourceFile, not the 1-based line number. If the source_file is empty or the position is located before the first line, None is returned.

pub fn line_bounds(&self, line_index: usize) -> (BytePos, BytePos)

pub fn contains(&self, byte_pos: BytePos) -> bool

Trait Implementations

impl Archive for SourceFile

where Arc<FileName>: Archive, bool: Archive, Option<Arc<FileName>>: Archive, u32: Archive, With<Arc<String>, EncodeArcString>: Archive, u128: Archive, BytePos: Archive, Vec<BytePos>: Archive, Vec<MultiByteChar>: Archive, Vec<NonNarrowChar>: Archive,

type Archived = ArchivedSourceFile

The archived representation of this type.

type Resolver = SourceFileResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

unsafe fn resolve( &self, pos: usize, resolver: <SourceFile as Archive>::Resolver, out: *mut <SourceFile as Archive>::Archived, )

Creates the archived version of this value at the given position and writes it to the given output.

impl Clone for SourceFile

fn clone(&self) -> SourceFile

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SourceFile

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

Formats the value using the given formatter.

impl<__D> Deserialize<SourceFile, __D> for <SourceFile as Archive>::Archived

where __D: Fallible + ?Sized, Arc<FileName>: Archive, <Arc<FileName> as Archive>::Archived: Deserialize<Arc<FileName>, __D>, bool: Archive, <bool as Archive>::Archived: Deserialize<bool, __D>, Option<Arc<FileName>>: Archive, <Option<Arc<FileName>> as Archive>::Archived: Deserialize<Option<Arc<FileName>>, __D>, u32: Archive, <u32 as Archive>::Archived: Deserialize<u32, __D>, With<Arc<String>, EncodeArcString>: Archive, <With<Arc<String>, EncodeArcString> as Archive>::Archived: Deserialize<With<Arc<String>, EncodeArcString>, __D>, u128: Archive, <u128 as Archive>::Archived: Deserialize<u128, __D>, BytePos: Archive, <BytePos as Archive>::Archived: Deserialize<BytePos, __D>, Vec<BytePos>: Archive, <Vec<BytePos> as Archive>::Archived: Deserialize<Vec<BytePos>, __D>, Vec<MultiByteChar>: Archive, <Vec<MultiByteChar> as Archive>::Archived: Deserialize<Vec<MultiByteChar>, __D>, Vec<NonNarrowChar>: Archive, <Vec<NonNarrowChar> as Archive>::Archived: Deserialize<Vec<NonNarrowChar>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<SourceFile, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl<'a> From<&'a SourceFile> for StringInput<'a>

Creates an Input from SourceFile. This is an alias for

   StringInput::new(&fm.src, fm.start_pos, fm.end_pos)

fn from(fm: &'a SourceFile) -> StringInput<'a>

Converts to this type from the input type.

impl<__S> Serialize<__S> for SourceFile

where __S: Fallible + ?Sized, Arc<FileName>: Serialize<__S>, bool: Serialize<__S>, Option<Arc<FileName>>: Serialize<__S>, u32: Serialize<__S>, With<Arc<String>, EncodeArcString>: Serialize<__S>, u128: Serialize<__S>, BytePos: Serialize<__S>, Vec<BytePos>: Serialize<__S>, Vec<MultiByteChar>: Serialize<__S>, Vec<NonNarrowChar>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<SourceFile as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
