Struct Pdb

pub struct Pdb<F = RandomAccessFile> { /* private fields */ }

Allows reading the contents of a PDB file.

This type provides read-only access. It does not provide any means to modify a PDB file or to create a new one.

Implementations

impl<F: ReadAt> Pdb<F>

pub fn read_dbi_stream_header(&self) -> Result<DbiStreamHeader>

Reads the header of the DBI stream. This does not validate the header.

pub fn read_dbi_stream(&self) -> Result<DbiStream<Vec<u8>>, Error>

Reads the entire DBI Stream, validates the header, and then returns an object that can be used for further queries of the DBI Stream.

pub fn read_modules(&self) -> Result<ModInfoSubstream<Vec<u8>>>

Reads the module substream data from the DBI stream.

This function always reads the data from the file. It does not cache the data.

pub fn modules(&self) -> Result<&ModInfoSubstream<Vec<u8>>>

Gets access to the DBI Modules Substream. This will read the DBI Modules Substream on-demand, and will cache it.

pub fn read_sources_data(&self) -> Result<Vec<u8>>

Reads the DBI Sources Substream. This always reads the data, and does not cache it.

pub fn sources_data(&self) -> Result<&[u8]>

Gets access to the DBI Sources Substream data.

pub fn sources(&self) -> Result<DbiSourcesSubstream<'_>>

Gets access to the DBI Sources Substream and parses the header.

pub fn drop_sources(&mut self)

Drops the cached DBI Sources Substream data, if any.

pub fn read_section_contributions(&self) -> Result<Vec<u8>>

Reads the contents of the DBI Section Contributions Substream. This function never caches the data; it is always read unconditionally.

impl<F: ReadAt> Pdb<F>

pub fn read_gss(&self) -> Result<GlobalSymbolStream>

Reads the Global Symbol Stream (GSS). This stream contains global symbol records.

This function does not validate the contents of the stream.

pub fn read_gsi(&self) -> Result<GlobalSymbolIndex>

Reads the Global Symbol Index (GSI). This stream contains a name-to-symbol lookup table. It indexes many global symbols, such as S_GPROCREF, S_CONSTANT, etc.

pub fn read_psi(&self) -> Result<PublicSymbolIndex>

Reads the Public Symbol Index.

impl<F: ReadAt> Pdb<F>

pub fn read_module_stream( &self, mod_info: &ModuleInfo<'_>, ) -> Result<Option<ModiStreamData<StreamData>>, Error>

Reads a Module Info stream. The caller must provide a ModuleInfo structure, which comes from the DBI Stream. Use crate::dbi::read_dbi_stream to enumerate ModuleInfo values.

If the Module Info record has a NIL stream, then this function returns Ok(None).

impl<F: ReadAt> Pdb<F>

pub fn add_embedded_source( &mut self, file_path: &str, file_contents: &[u8], ) -> Result<bool>

where F: WriteAt,

Embeds the contents of a source file into the PDB.

pub fn add_or_replace_named_stream( &mut self, stream_name: &str, stream_contents: &[u8], ) -> Result<bool>

where F: WriteAt,

Sets the contents of a named stream to the given value.

If there is already a named stream with the given name, then the stream’s contents are replaced with stream_contents. First, though, this function reads the contents of the existing stream and compares them to stream_contents. If they are identical, then the stream is not modified and this function will return Ok(true). If the contents are not identical, then this function returns Ok(true).

If there is not already a named stream with given name, then a new stream is created and an entry is added to the Named Streams Map. In this case, the function returns Ok(false).

impl<F: ReadAt> Pdb<F>

pub fn read_type_stream(&self) -> Result<TypeStream<Vec<u8>>>

Reads the TPI or IPI stream.

pub fn flush_all(&mut self) -> Result<bool>

where F: WriteAt,

Writes any changes that have been buffered in memory to disk. However, this does not commit the changes. It is still necessary to call the commit() method.
