Required Methods

Provided Methods

returns all buffers, as organized by Rust (i.e. null buffer is skipped)

Returns the length, in bytes, of the buffer i (indexed according to the C data interface)

returns the null bit buffer. Rust implementation uses a buffer that is not part of the array of buffers. The C Data interface’s null buffer is part of the array of buffers.
