Crate csv_line

Fast deserialization of a single CSV line.

Usage

#[derive(Debug, PartialEq, serde::Deserialize)]
struct Foo(String, i32);

assert_eq!(
    csv_line::from_str::<Foo>("foo,42").unwrap(),
    Foo("foo".into(), 42)
);
assert_eq!(
    csv_line::from_str_sep::<Foo>("foo 42", ' ').unwrap(),
    Foo("foo".into(), 42)
);

Speed

The performance is comparable to serde_json (lower is better):

test csv_builder ... bench:      13,190.73 ns/iter (+/- 793.61)
test csv_core    ... bench:      12,840.18 ns/iter (+/- 633.12)
test csv_line    ... bench:         176.50 ns/iter (+/- 5.15)
test serde_json  ... bench:          88.24 ns/iter (+/- 2.12
