Struct AdapterStack 

pub struct AdapterStack {
    pub adapters: Vec<AdapterRef>,
}

Adapter composition: apply multiple LoRA adapters in sequence.

Allows stacking several adapters with independent blending weights. Weights can be normalized so they sum to 1.0, which is useful for even blending across adapters.

Fields

adapters: Vec<AdapterRef>

The ordered list of adapters to apply.

Implementations

impl AdapterStack

pub fn new() -> Self

Create an empty adapter stack.

pub fn add(self, name: impl Into<String>, weight: f32) -> Self

Add an adapter with the given blending weight.

pub fn len(&self) -> usize

Number of adapters in the stack.

pub fn is_empty(&self) -> bool

Whether the stack is empty.

pub fn total_weight(&self) -> f32

Sum of all adapter weights.

pub fn normalize_weights(&mut self)

Normalize weights so they sum to 1.0.

If the total weight is zero (or very close to it), weights are left unchanged to avoid division by zero.

Trait Implementations
