Struct Header 

pub struct Header {
    pub voxel_to_rasmm: [[f64; 4]; 4],
    pub dimensions: [u64; 3],
    pub nb_streamlines: u64,
    pub nb_vertices: u64,
    pub extra: HashMap<String, Value>,
}

TRX file header (stored as JSON in header.json).

Fields

voxel_to_rasmm: [[f64; 4]; 4]

4x4 affine matrix mapping voxel coordinates to RAS+mm space. Stored row-major as [[f64; 4]; 4].

dimensions: [u64; 3]

Volume dimensions [x, y, z].

nb_streamlines: u64

Total number of streamlines.

nb_vertices: u64

Total number of vertices (points) across all streamlines.

extra: HashMap<String, Value>

Any extra fields not covered above.

Implementations

impl Header

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

Read header from a header.json file.

pub fn to_json(&self) -> Result<String>

Serialize header to JSON string.

pub fn write_to(&self, path: &Path) -> Result<()>

Write header to a file.

pub fn identity_affine() -> [[f64; 4]; 4]

Identity affine (no transform).

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Header

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Header

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Header

fn eq(&self, other: &Header) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Header

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
