Struct StarFilter 

pub struct StarFilter(/* private fields */);

Implementations

impl StarFilter

pub fn call(&self, s: &Star, n: usize) -> bool

Invoke the filter

pub fn then(&mut self, f: StarFilter) -> &mut Self

Create a new filter that calls the current filter, an if true calls a follow-on filter

pub fn select(skip: usize, limit: usize) -> Self

Create a new filter that returns true after the first skip entries up to limit

This can be used to capture a subset of star results, for example

pub fn brighter_than(magnitude: f32) -> Self

Create a new filter that returns true for stars brighter than a certain magnitude

pub fn cos_to_gt(v: [f64; 3], cos: f64) -> Self

Create a new filter that returns true for stars that are closer in angle to a (unit) vector than a specified angle (this being given by its cosine)

Returns the “default value” for a type.

impl<F: StarFilterFn + 'static> From<F> for StarFilter
