pub struct Pdf { /* private fields */ }

Wrapper to an LHAPDF object of the type LHAPDF::PDF.

Implementations

impl Pdf

pub fn with_lhaid(lhaid: i32) -> Result<Self>

Constructor. Create a new PDF with the given lhaid ID code.

Errors

TODO

pub fn with_setname_and_member(setname: &str, member: i32) -> Result<Self>

Constructor. Create a new PDF with the given PDF setname and member ID.

Errors

TODO

pub fn with_setname_and_nmem(setname_nmem: &str) -> Result<Self>

Create a new PDF with the given PDF set name and member ID as a single string.

The format of the setname_nmem string is <setname>/<nmem> where <nmem> must be parseable as a positive integer. The / character is not permitted in set names due to clashes with Unix filesystem path syntax.

If no /<nmem> is given, member number 0 will be used.

Errors

TODO

pub fn xfx_q2(&self, id: i32, x: f64, q2: f64) -> f64

Get the PDF x * f(x) value at x and q2 for the given PDG ID.

Panics

If the value of either x or q2 is not within proper boundaries this method will panic.

pub fn alphas_q2(&self, q2: f64) -> f64

Value of of the strong coupling at q2 used by this PDF.

Panics

If the value of q2 is not within proper boundaries this method will panic.

pub fn set(&self) -> PdfSet

Get the info class that actually stores and handles the metadata.

pub fn x_min(&mut self) -> f64

Minimum valid x value for this PDF.

pub fn x_max(&mut self) -> f64

Maximum valid x value for this PDF.

pub fn set_force_positive(&mut self, mode: i32)

Set whether the PDF will only return positive (definite) values or not.

pub fn force_positive(&mut self) -> i32

Check whether the PDF is set to only return positive (definite) values or not.

This is to avoid overshooting in to negative values when interpolating/extrapolating PDFs that sharply decrease towards zero. 0 = unforced, 1 = forced positive, 2 = forced positive definite (>= 1e-10).

pub fn flavors(&self) -> Vec<i32>

List of flavours defined by this Pdf set.

pub fn set_flavors(&mut self, flavors: &[i32])

Manually set/override the list of flavours defined by this Pdf set.
