Struct DictionaryLines 

pub struct DictionaryLines<'a> { /* private fields */ }

Several field lines read as one Dictionary.

Examples

use parse_net::sfv::{self, BareItem, Member};

let lines: [&[u8]; 2] = [b"a=1", b"b=2, a=3"];
let d = sfv::parse_dictionary_lines(&lines)?;
assert_eq!(d.len(), 3);
assert!(matches!(d.get("a"), Some(Member::Item(i)) if i.bare == BareItem::Integer(3)));

Implementations

impl<'a> DictionaryLines<'a>

pub fn iter(&self) -> impl Iterator<Item = (&'a str, Member<'a>)> + use<'a>

The members of every line, in order.

Examples

let lines: [&[u8]; 2] = [b"a=1", b"b=2, a=3"];
let d = parse_net::sfv::parse_dictionary_lines(&lines)?;
assert!(d.iter().map(|(k, _)| k).eq(["a", "b", "a"]));

pub fn get(&self, key: &str) -> Option<Member<'a>>

The member for key: the last occurrence across every line.

Examples

use parse_net::sfv::{self, BareItem, Member};

let lines: [&[u8]; 2] = [b"a=1, b", b"a=2"];
let d = sfv::parse_dictionary_lines(&lines)?;
assert!(matches!(d.get("a"), Some(Member::Item(i)) if i.bare == BareItem::Integer(2)));
assert!(d.get("c").is_none());

pub const fn len(&self) -> usize

The number of members across every line, repeats included.

Examples

let lines: [&[u8]; 2] = [b"a=1, b", b"a=2"];
assert_eq!(parse_net::sfv::parse_dictionary_lines(&lines)?.len(), 3);

pub const fn is_empty(&self) -> bool

Whether no line has a member.

Examples

let lines: [&[u8]; 1] = [b"a"];
assert!(!parse_net::sfv::parse_dictionary_lines(&lines)?.is_empty());
