blobCreateSubBlob harfbuzz.blob.Blob blobCreateSubBlob(harfbuzz.blob.Blob parent, uint offset, uint length): Returns a blob that represents a range of bytes in parent. The new blob is always created with #HB_MEMORY_MODE_READONLY, meaning that it will never modify data in the parent blob. The parent data is not expected to be modified, and will result in undefined behavior if it is.
blobGetData string blobGetData(harfbuzz.blob.Blob blob): Fetches the data from a blob.
blobGetDataWritable string blobGetDataWritable(harfbuzz.blob.Blob blob): Tries to make blob data writable (possibly copying it) and return pointer to data.

bufferAdd void bufferAdd(harfbuzz.buffer.Buffer buffer, harfbuzz.types.Codepoint codepoint, uint cluster): Appends a character with the Unicode value of codepoint to buffer, and gives it the initial cluster value of cluster. Clusters can be any thing the client wants, they are usually used to refer to the index of the character in the input text stream and are output in #hb_glyph_info_t.cluster field.
bufferAddCodepoints void bufferAddCodepoints(harfbuzz.buffer.Buffer buffer, harfbuzz.types.Codepoint[] text, uint itemOffset, int itemLength): Appends characters from text array to buffer. The item_offset is the position of the first character from text that will be appended, and item_length is the number of character. When shaping part of a larger text (e.g. a run of text from a paragraph), instead of passing just the substring corresponding to the run, it is preferable to pass the whole paragraph and specify the run start and length as item_offset and item_length, respectively, to give HarfBuzz the full context to be able, for example, to do cross-run Arabic shaping or properly handle combining marks at stat of run.
bufferAddLatin1 void bufferAddLatin1(harfbuzz.buffer.Buffer buffer, ubyte[] text, uint itemOffset, int itemLength): Similar to harfbuzz.global.bufferAddCodepoints, but allows only access to first 256 Unicode code points that can fit in 8-bit strings.

bufferDiff harfbuzz.types.BufferDiffFlags bufferDiff(harfbuzz.buffer.Buffer buffer, harfbuzz.buffer.Buffer reference, harfbuzz.types.Codepoint dottedcircleGlyph, uint positionFuzz): If dottedcircle_glyph is (hb_codepoint_t) -1 then #HB_BUFFER_DIFF_FLAG_DOTTED_CIRCLE_PRESENT and #HB_BUFFER_DIFF_FLAG_NOTDEF_PRESENT are never returned. This should be used by most callers if just comparing two buffers is needed.

A buffer gains position data when harfbuzz.global.bufferGetGlyphPositions is called on it, and cleared of position data when harfbuzz.global.bufferClearContents is called.
bufferNormalizeGlyphs void bufferNormalizeGlyphs(harfbuzz.buffer.Buffer buffer): Reorders a glyph buffer to have canonical in-cluster glyph order / position. The resulting clusters should behave identical to pre-reordering clusters.

bufferSerializeFormatFromString harfbuzz.types.BufferSerializeFormat bufferSerializeFormatFromString(ubyte[] str): Parses a string into an #hb_buffer_serialize_format_t.

bufferSetContentType void bufferSetContentType(harfbuzz.buffer.Buffer buffer, harfbuzz.types.BufferContentType contentType): Sets the type of buffer contents. Buffers are either empty, contain characters (before shaping), or contain glyphs (the result of shaping).
bufferSetDirection void bufferSetDirection(harfbuzz.buffer.Buffer buffer, harfbuzz.types.Direction direction): Set the text flow direction of the buffer. No shaping can happen without setting buffer direction, and it controls the visual direction for the output glyphs; for RTL direction the glyphs will be reversed. Many layout features depend on the proper setting of the direction, for example, reversing RTL text before shaping, then shaping with LTR direction is not the same as keeping the text in logical order and shaping with RTL direction.
