[−][src]Trait rubric::results_file::AsCsv
Trait to convert a struct to csv (comma separated values).
You should not append a newline for any of these functions.
Example Implementation
use rubric::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) -> String { String::from("x,y") } } let p = Point { x: 4, y: 8 }; assert_eq!(p.header(), "x,y"); 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) -> String
The header for the csv file. Should match the fields
in as_csv()
Implementors
impl AsCsv for Submission
[src]
fn as_csv(&self) -> String
[src]
Returns the submission's values in csv format. The TestData
atttached will be
sorted alphabetically by key.
fn filename(&self) -> String
[src]
Returns the filename to use when writing submissions to disk
fn header(&self) -> String
[src]
Returns a header of all the fields, matching the data in as_csv
impl AsCsv for TestData
[src]
fn as_csv(&self) -> String
[src]
Returns the test data, serialized to a csv string. It will be sorted alphabetically by key.
fn filename(&self) -> String
[src]
Returns the filename that the ResultsFile
uses as its output
This probably shouldn't get used for test data, as it will be written as part of a submission, not on it's own.
fn header(&self) -> String
[src]
Returns a header to write to a csv file. This should match the fields in as_csv
above.
