pub struct ScalaSignatureReader { /* private fields */ }Expand description
Reader for the Scala 2 signature binary format.
Parses the binary entry table from raw @ScalaSignature bytes and provides
accessors for individual entries, name resolution, and symbol info extraction.
Implementations§
Source§impl ScalaSignatureReader
impl ScalaSignatureReader
Sourcepub fn parse(bytes: &[u8]) -> Option<Self>
pub fn parse(bytes: &[u8]) -> Option<Self>
Parse a Scala signature from raw bytes.
Returns None if the bytes are too short, the version is unsupported,
or the entry table is malformed.
Sourcepub fn entry_count(&self) -> usize
pub fn entry_count(&self) -> usize
Return the number of entries in the table.
Sourcepub fn entry(&self, index: usize) -> Option<&SignatureEntry>
pub fn entry(&self, index: usize) -> Option<&SignatureEntry>
Get entry at the given index.
Sourcepub fn read_name(&self, index: usize) -> Option<String>
pub fn read_name(&self, index: usize) -> Option<String>
Read a name from a TERMname or TYPEname entry.
Returns None if the index is out of bounds or the entry is not a name.
Sourcepub fn read_symbol_info(
&self,
entry: &SignatureEntry,
) -> Option<ScalaSymbolInfo>
pub fn read_symbol_info( &self, entry: &SignatureEntry, ) -> Option<ScalaSymbolInfo>
Read symbol info from a CLASSsym or MODULEsym entry.
The symbol info format is:
name_ref (Nat) | owner_ref (Nat) | flags (LongNat) | [private_within_ref (Nat)] | info_ref (Nat)Returns None if the entry data is malformed.
Sourcepub fn resolve_qualified_name(&self, sym_index: usize) -> Option<String>
pub fn resolve_qualified_name(&self, sym_index: usize) -> Option<String>
Resolve the fully qualified name of a symbol by walking the owner chain.
Returns None if the chain cannot be resolved (e.g., missing entries).
Sourcepub fn read_ext_ref_owner(&self, entry: &SignatureEntry) -> Option<usize>
pub fn read_ext_ref_owner(&self, entry: &SignatureEntry) -> Option<usize>
Read the owner index from an EXTref or EXTMODCLASSref entry.
Returns None if there is no owner reference (only a name reference)
or the entry is not an external reference.
Sourcepub fn class_and_module_symbols(&self) -> Vec<(usize, &SignatureEntry)>
pub fn class_and_module_symbols(&self) -> Vec<(usize, &SignatureEntry)>
Find all CLASSsym and MODULEsym entries and their indices.
Sourcepub fn ext_refs(&self) -> Vec<(usize, &SignatureEntry)>
pub fn ext_refs(&self) -> Vec<(usize, &SignatureEntry)>
Find all EXTref and EXTMODCLASSref entries and their indices.
