Struct DiskAnnOptions 

pub struct DiskAnnOptions {
    pub r: usize,
    pub l: usize,
    pub beam_width: usize,
    pub alpha: u32,
}

DiskANN (Vamana) build parameters.

Fields

r: usize

Maximum graph degree R (the robust-prune degree bound). Default 64.

l: usize

Search-list size L during build (controls build quality/time). Default 128. Must be >= r.

beam_width: usize

Search beam width at query time (number of candidate vectors fetched per I/O round). Default 8.

alpha: u32

Robust-prune distance threshold alpha × 100 (stored as integer for Eq; 120 = alpha 1.2). Default 120. Range [100, 300].
