Struct StationOrientation 

#[non_exhaustive]
pub struct StationOrientation {
    pub axis: Option<DVec3>,
    pub ref_direction: Option<DVec3>,
}

An explicit in-section orientation at a station (#246).

Both vectors are components in the station’s base frame, (tangent, lateral, up); see the module documentation for their meaning, defaults and orthonormalisation. Both absent is the base frame itself, the Default.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

axis: Option<DVec3>

The oriented frame’s up (local Z), exact; None for (0, 0, 1).

ref_direction: Option<DVec3>

The direction the oriented frame’s tangent role (local X) is taken from, made perpendicular to the axis; None for (1, 0, 0).

Implementations

impl StationOrientation

pub const fn new( axis: Option<DVec3>, ref_direction: Option<DVec3>, ) -> StationOrientation

An orientation from an optional axis and reference direction, both in the base frame.

pub const fn is_base(&self) -> bool

Whether neither vector is given, so the base frame is used as is.

pub fn unit_axes(&self) -> Result<(DVec3, DVec3), &'static str>

The unit axis and unit reference direction, defaults filled in.

Errors

Why there are none, worded for GraphError::InvalidStation: a zero or non-finite vector, or the two parallel or anti-parallel within ORIENTATION_TOLERANCE.
