Implementations

impl TimsDataLoader

pub fn new_lazy( bruker_lib_path: &str, data_path: &str, use_bruker_sdk: bool, scan_max_index: u32, im_lower: f64, im_upper: f64, tof_max_index: u32, mz_lower: f64, mz_upper: f64, ) -> Self

pub fn new_in_memory( bruker_lib_path: &str, data_path: &str, use_bruker_sdk: bool, scan_max_index: u32, im_lower: f64, im_upper: f64, tof_max_index: u32, mz_lower: f64, mz_upper: f64, ) -> Self

pub fn new_lazy_with_calibration( data_path: &str, tof_max_index: u32, mz_lower: f64, mz_upper: f64, im_lookup: Vec<f64>, ) -> Self

Create a lazy loader with pre-computed ion mobility calibration lookup table.

This method enables accurate ion mobility calibration with fast parallel extraction. The im_lookup table should be pre-computed using the Bruker SDK.

Arguments

• data_path - Path to the .d folder
• tof_max_index - Maximum TOF index (from GlobalMetaData)
• mz_lower - Minimum m/z value (from GlobalMetaData)
• mz_upper - Maximum m/z value (from GlobalMetaData)
• im_lookup - Pre-computed scan→1/K0 lookup table

Returns

A new TimsDataLoader with LookupIndexConverter

pub fn new_in_memory_with_calibration( data_path: &str, tof_max_index: u32, mz_lower: f64, mz_upper: f64, im_lookup: Vec<f64>, ) -> Self

Create an in-memory loader with pre-computed ion mobility calibration lookup table.

This method enables accurate ion mobility calibration with fast parallel extraction. The im_lookup table should be pre-computed using the Bruker SDK.

Arguments

• data_path - Path to the .d folder
• tof_max_index - Maximum TOF index (from GlobalMetaData)
• mz_lower - Minimum m/z value (from GlobalMetaData)
• mz_upper - Maximum m/z value (from GlobalMetaData)
• im_lookup - Pre-computed scan→1/K0 lookup table

Returns

A new TimsDataLoader with LookupIndexConverter

pub fn new_lazy_with_mz_calibration( data_path: &str, tof_intercept: f64, tof_slope: f64, im_min: f64, im_max: f64, scan_max_index: u32, ) -> Self

Create a lazy loader with full calibration (both m/z and IM).

This method uses regression-derived m/z calibration coefficients instead of the simple boundary model, providing more accurate m/z conversion.

Arguments

• data_path - Path to the .d folder
• tof_intercept - Intercept for sqrt(mz) = intercept + slope * tof
• tof_slope - Slope for sqrt(mz) = intercept + slope * tof
• im_min - Minimum 1/K0 value
• im_max - Maximum 1/K0 value
• scan_max_index - Maximum scan index

pub fn new_in_memory_with_mz_calibration( data_path: &str, tof_intercept: f64, tof_slope: f64, im_min: f64, im_max: f64, scan_max_index: u32, ) -> Self

Create an in-memory loader with full calibration (both m/z and IM).

This method uses regression-derived m/z calibration coefficients instead of the simple boundary model, providing more accurate m/z conversion.

pub fn get_index_converter(&self) -> &dyn IndexConverter

pub fn uses_bruker_sdk(&self) -> bool

Check if the Bruker SDK is being used for index conversion. The Bruker SDK is NOT thread-safe, so parallel operations that call the index converter must be disabled when using the SDK.
