Implementations

impl LinuxAlignedFileReader

AlignedFileReader for Linux. When you modify this class run the benchmarks to make sure we don’t regress on runtime.

Run this before making code your change

cargo bench –bench bench_main -p diskann – –save-baseline prior_to_change

Run this after making your code change to generate comparison metrics

Trait Implementations

impl AlignedFileReader for LinuxAlignedFileReader

type Alignment = A512

O_DIRECT requires the buffer pointer to be aligned to the device sector size in memory (512 bytes on typical Linux block devices).

fn read( &mut self, read_requests: &mut [AlignedRead<'_, u8, A512>], ) -> ANNResult<()>

Read the data from the file by sending concurrent io requests in batches.
