Trait Implementations
impl<'a> ArrowArrayRef for ArrowArrayChild<'a>
[src]
impl<'a> ArrowArrayRef for ArrowArrayChild<'a>
[src]fn array(&self) -> &FFI_ArrowArray
[src]
fn schema(&self) -> &FFI_ArrowSchema
[src]
fn owner(&self) -> &Arc<FFI_ArrowArray>
[src]
fn to_data(&self) -> Result<ArrayData>
[src]
fn buffers(&self) -> Result<Vec<Buffer>>
[src]
fn buffers(&self) -> Result<Vec<Buffer>>
[src]returns all buffers, as organized by Rust (i.e. null buffer is skipped)
fn buffer_len(&self, i: usize) -> Result<usize>
[src]
fn buffer_len(&self, i: usize) -> Result<usize>
[src]Returns the length, in bytes, of the buffer i
(indexed according to the C data interface)
fn null_bit_buffer(&self) -> Option<Buffer>
[src]
fn null_bit_buffer(&self) -> Option<Buffer>
[src]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. Read more
