Provides read only access to a subclass of BinaryStream.

LLVM_ABI Error readStreamRef(BinaryStreamRef &Ref)

Read the entire remainder of the underlying stream into Ref.

Error readObject(const T *&Dest)

Get a pointer to an object of type T from the underlying stream, as if by memcpy, and store the resul...

Error readInteger(T &Dest)

Read an integer of the specified endianness into Dest and update the stream's offset.

LLVM_ABI std::pair< BinaryStreamReader, BinaryStreamReader > split(uint64_t Offset) const

Error readArray(ArrayRef< T > &Array, uint32_t NumElements)

Get a reference to a NumElements element array of objects of type T from the underlying stream as if ...

BinaryStreamRef is to BinaryStream what ArrayRef is to an Array.

Lightweight error class with error context and mandatory checking.

static ErrorSuccess success()

Create a success value.

Tagged union holding either a T or a Error.

FixedStreamArray is similar to VarStreamArray, except with each record having a fixed-length.

StringRef - Represent a constant reference to a string, i.e.
