Struct StructuredSourceMap 

pub struct StructuredSourceMap { /* private fields */ }

A single source map in structured form. See the module documentation.

Implementations

impl StructuredSourceMap

pub fn from_swc_map(map: SourceMap) -> Result<Self>

Builds from a [swc_sourcemap::SourceMap], taking the sourcesContent entries out of the map before serializing the (now small) remainder. This is the cheap constructor for all internally generated maps: the source text is escaped exactly once and never round-trips through JSON parsing.

pub fn from_json(map: &Rope) -> Result<Self>

Parses an arbitrary serialized source map, e.g. one shipped alongside external code.

pub fn from_json_slice(map: &[u8]) -> Result<Self>

Parses a serialized source map from a byte slice.

pub fn from_serialize<T: Serialize>(value: &T) -> Result<Self>

Builds directly from a value’s serde::Serialize implementation (e.g. swc_sourcemap::lazy::RawSourceMap), capturing each top-level field’s serialized JSON value without materializing — and then re-parsing — the whole document. The result is byte-equivalent to Self::from_json_slice(&serde_json::to_vec(value)?).

Errors if the value does not serialize as a struct or contains a field this type does not know about; callers should fall back to serializing and Self::from_json then.

pub fn rewrite_sources( &self, rewrite: impl FnMut(&str) -> Result<Option<String>>, ) -> Result<Self>

Rewrites each sources entry, keeping every other field (including the shared sourcesContent ropes) intact. rewrite returns None to leave an entry unchanged.

sources is only decoded if a rewrite actually changes an entry; if it cannot be decoded (e.g. non-string entries in an external map) the map is returned unchanged.

pub fn to_rope(&self) -> Rope

Serializes the map. Field order matches swc_sourcemap’s serializer; sourcesContent and mappings ropes are shared, not copied, into the result.

Trait Implementations

impl<'__de, __Context> BorrowDecode<'__de, __Context> for StructuredSourceMap

fn borrow_decode<__D: BorrowDecoder<'__de, Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given BorrowDecode.

impl Clone for StructuredSourceMap

fn clone(&self) -> StructuredSourceMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StructuredSourceMap

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

Formats the value using the given formatter.

impl<__Context> Decode<__Context> for StructuredSourceMap

fn decode<__D: Decoder<Context = __Context>>( decoder: &mut __D, ) -> Result<Self, DecodeError>

Attempt to decode this type with the given Decode.

impl Default for StructuredSourceMap

fn default() -> StructuredSourceMap

Returns the “default value” for a type.

impl DeterministicHash for StructuredSourceMap

fn deterministic_hash<H: DeterministicHasher>(&self, state: &mut H)

Adds self’s bytes to the DeterministicHasher’s state, in a way that is replicatable on any platform or process run.

impl Encode for StructuredSourceMap

fn encode<__E: Encoder>(&self, encoder: &mut __E) -> Result<(), EncodeError>

Encode a given type.

impl Eq for StructuredSourceMap

impl From<StructuredSourceMap> for SectionMap

fn from(map: StructuredSourceMap) -> Self

Converts to this type from the input type.

impl NonLocalValue for StructuredSourceMap

impl PartialEq for StructuredSourceMap

fn eq(&self, other: &StructuredSourceMap) -> 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 StructuralPartialEq for StructuredSourceMap

impl TraceRawVcs for StructuredSourceMap

fn trace_raw_vcs(&self, __context__: &mut TraceRawVcsContext)

fn get_raw_vcs(&self) -> Vec<RawVc>
