[−][src]Trait lab_grader::results_file::AsCsv
Trait to convert a struct to csv (comma separated values).
Example Implementation
use lab_grader::results_file::AsCsv; // A dummy struct so we can impl AsCsv pub struct Point { x: i32, y: i32 } impl AsCsv for Point { fn as_csv(&self) -> String { format!("{},{}", self.x, self.y) } fn filename(&self) -> String { String::from("points.csv") } fn header(&self) -> &'static str { "x,y\n" } } let p = Point { x: 4, y: 8 }; assert_eq!(p.header(), "x,y\n"); assert_eq!(p.filename(), "points.csv"); assert_eq!(p.as_csv(), "4,8");
Required methods
fn as_csv(&self) -> String
The item in CSV format. This should not append a newline.
fn filename(&self) -> String
The filename where this type should be saved.
Usually this should just be <item>.csv
fn header(&self) -> &'static str
The header for the csv file. Should match the fields
in as_csv()
