Enum AnyTrxFile 

pub enum AnyTrxFile {
    F16(TrxFile<f16>),
    F32(TrxFile<f32>),
    F64(TrxFile<f64>),
}

A type-erased TRX container that can hold any position dtype.

Use this when the position dtype is not known at compile time (e.g. CLI tools that accept arbitrary .trx files).

Variants

F16(TrxFile<f16>)

F32(TrxFile<f32>)

F64(TrxFile<f64>)

Implementations

impl AnyTrxFile

pub fn load(path: &Path) -> Result<Self>

Load a TRX file, detecting the positions dtype at runtime.

pub fn positions_ref(&self) -> PositionsRef<'_>

Get a reference to the positions, dispatched by dtype.

pub fn dtype(&self) -> DType

The positions dtype.

pub fn header(&self) -> &Header

The header.

pub fn nb_streamlines(&self) -> usize

Number of streamlines.

pub fn nb_vertices(&self) -> usize

Number of vertices.

pub fn with_typed<R>( &self, on_f16: impl FnOnce(&TrxFile<f16>) -> R, on_f32: impl FnOnce(&TrxFile<f32>) -> R, on_f64: impl FnOnce(&TrxFile<f64>) -> R, ) -> R

Dispatch to a closure with a concrete &TrxFile<P>.

pub fn positions_f32(&self) -> Vec<[f32; 3]>

pub fn scalar_dpv_f32(&self, name: &str) -> Result<Vec<f32>>

pub fn scalar_dps_f32(&self, name: &str) -> Result<Vec<f32>>

pub fn with_updated_header(self, header: Header) -> Self
