Struct swc_common::source_map::BytePos

pub struct BytePos(pub u32);

A byte offset. Keep this small (currently 32-bits), as AST contains a lot of them.

Reserved

• 0 is reserved for dummy spans. It means BytePos(0) means the BytePos is synthesized by the compiler.

• Values larger than u32::MAX - 2^16 are reserved for the comments.

u32::MAX is special value used to generate source map entries.

Tuple Fields

0: u32

Implementations

impl BytePos

pub const DUMMY: Self = _

Dummy position. This is reserved for synthesized spans.

pub const SYNTHESIZED: Self = _

Synthesized, but should be stored in a source map.

pub const fn is_reserved_for_comments(self) -> bool

pub const fn is_dummy(self) -> bool

Returns `true`` if this is synthesized and has no relevant input source code.

pub const fn can_have_comment(self) -> bool

Returns `true`` if this is explicitly synthesized or has relevant input source so can have a comment.

Trait Implementations

impl Add<BytePos> for NonNarrowChar

type Output = NonNarrowChar

The resulting type after applying the + operator.

fn add(self, rhs: BytePos) -> Self

Performs the + operation.

impl Add for BytePos

fn add(self, rhs: BytePos) -> BytePos

Performs the + operation.

impl Archive for BytePos

type Archived = ArchivedBytePos

fn clone(&self) -> BytePos

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BytePos

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

Formats the value using the given formatter.

impl Default for BytePos

fn default() -> BytePos

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for BytePos

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

impl Ord for BytePos

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

fn eq(&self, other: &BytePos) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for BytePos

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

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

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