阅读更多关于 Using 'fastmatch' package in R

问题 I have to find indices for 1MM numeric values within a vector of roughly 10MM values. I found the package fastmatch , but when I use the function fmatch() , I am only returning the index of the first match. Can someone help me use this function to find all values, not just the first? I realize this is a basic question but online documentation is pretty sparse and fmatch has cut down the computing time considerably. Thanks so much! Here is some sample data - for the purposes of this exercise,

问题 Apology if the problemis trivial but as a python newby I wasn't able to find the right solution. I have two dataframes and I need to add a column to the first dataframe that is true if a certain value of the first dataframe is between two values of the second dataframe otherwise false. for example: first_df = pd.DataFrame({'code1':[1,1,2,2,3,1,1],'code2':[10,22,15,15,7,130,2]}) second_df = pd.DataFrame({'code1':[1,1,2,2,3,1,1],'code2_start':[5,20,11,11,5,110,220],'code2_end':[15,25,20,20,10

How do I pass an enum variant to match on as a function parameter?

阅读更多关于 How do I pass an enum variant to match on as a function parameter?

问题 I would like to pass in the parameters what arm of the enum I need to match, something like this: enum D { A(i64), B(u64), C(u64, u64), } let a = D.A(10); println!(a.is_of(D.A)); // true println!(a.is_of(D.B)); // false I know I can use matching rules for this, but I'd like this is_of method to take as an input of the enum options for my purposes. 回答1: You cannot. It is not possible to pass types as function parameters. Enum variants are not types to start with. If you are OK using a macro
