Struct SfParams 

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

Parameters of an item or an inner list. A repeated key keeps every occurrence; get takes the last, as RFC 9651 requires.

Examples

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

let params = sfv::parse_item(b"abc;a=1;b")?.params;
assert_eq!(params.len(), 2);
assert_eq!(params.get("a"), Some(BareItem::Integer(1)));
assert_eq!(params.get("b"), Some(BareItem::Boolean(true)));

Implementations

impl<'a> SfParams<'a>

pub fn iter(&self) -> ParamIter<'a>

The parameters, in order.

Examples

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

let params = sfv::parse_item(b"abc;a=1;b")?.params;
let mut it = params.iter();
assert_eq!(it.next(), Some(("a", BareItem::Integer(1))));
assert_eq!(it.next(), Some(("b", BareItem::Boolean(true))));
assert_eq!(it.next(), None);

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

The value of key: the last occurrence.

Examples

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

let params = sfv::parse_item(b"x;a=1;a=2")?.params;
assert_eq!(params.get("a"), Some(BareItem::Integer(2)));
assert_eq!(params.get("z"), None);

pub const fn len(&self) -> usize

The number of parameters, repeats included.

Examples

let params = parse_net::sfv::parse_item(b"x;a=1;a=2")?.params;
assert_eq!(params.len(), 2);

pub const fn is_empty(&self) -> bool

Whether there are no parameters.

Examples

use parse_net::sfv;

assert!(sfv::parse_item(b"x")?.params.is_empty());
assert!(!sfv::parse_item(b"x;a")?.params.is_empty());
