Reader

Helper container that manages changing position in the mmapped database file. It automatically handles moving the internal pointer forward when data is read to ensure proper alignment of data.

package

struct Reader {

ubyte[] data;

size_t current;

this(ubyte[] data, size_t startOffset = 0);

Reader newReader(size_t offset);

ubyte[] read(size_t length);

T read(size_t length);

T read(size_t length, T extrabits);

ubyte read();

}

Constructors

this this(ubyte[] data, size_t startOffset = 0): Constructs a new reader from a slice and a starting offset

Members

Functions

newReader Reader newReader(size_t offset): Creates a new reader at a different offset: used by the pointer and cache types to go fetch data outside of their own location.
read ubyte[] read(size_t length): Reads $length bytes from the database
read T read(size_t length): Reads $length bytes from the database and convert it to a native type of the appropriate endianness
read T read(size_t length, T extrabits): Reads $length byte into an integer type with the appropriate endianness and append extra most significant bits
read ubyte read(): Reads a single byte from the database

Variables

current size_t current;: Pointer to the current offset in the database file
data ubyte[] data;: The raw slice of the whole database
