Struct LoraConfig 

pub struct LoraConfig {
    pub rank: usize,
    pub alpha: f32,
    pub dropout: f32,
    pub target_modules: Vec<String>,
    pub fan_in_fan_out: bool,
}

Configuration for LoRA adaptation

Fields

rank: usize

Rank of the low-rank decomposition (typically 4-64)

alpha: f32

Scaling factor (typically equal to rank or 2*rank)

dropout: f32

Dropout probability for LoRA layers (0.0 = no dropout)

target_modules: Vec<String>

Which module names to apply LoRA to (e.g., “q_proj”, “v_proj”)

fan_in_fan_out: bool

Whether weight is stored as (fan_in, fan_out) instead of (fan_out, fan_in)
