Struct MatryoshkaSpec 

pub struct MatryoshkaSpec {
    pub truncation_dims: Vec<u32>,
}

Per-collection Matryoshka configuration.

Fields

truncation_dims: Vec<u32>

Sorted ascending list of valid truncation dimensions. E.g. for text-embedding-3 (1536-dim base): [256, 512, 1024, 1536].

Implementations

impl MatryoshkaSpec

pub fn new(truncation_dims: Vec<u32>) -> Self

Create a new spec. Sorts the provided dims ascending.

pub fn pick(&self, requested: Option<u32>) -> u32

Pick the largest supported dim ≤ requested.

Returns the full dim (last in the list) when requested is None. Returns the smallest available dim when requested is smaller than all supported dims.

pub fn is_valid(&self, dim: u32) -> bool

Return true if dim is one of the supported truncation dims.
