Struct IterState

pub(crate) struct IterState {
    state: State,
    html: bool,
    check_duplicates: bool,
    keys: Vec<Range<usize>>,
}

External iterator over spans of attribute key and value

Fields

state: State

Iteration state that determines what actions should be done before the actual parsing of the next attribute

html: bool

If true, enables ability to parse unquoted values and key-only (empty) attributes

check_duplicates: bool

If true, checks for duplicate names

keys: Vec<Range<usize>>

If check_duplicates is set, contains the ranges of already parsed attribute names. We store a ranges instead of slices to able to report a previous attribute position

Implementations

impl IterState

pub const fn new(offset: usize, html: bool) -> Self

fn recover(&self, slice: &[u8]) -> Option<usize>

Recover from an error that could have been made on a previous step. Returns an offset from which parsing should continue. If there no input left, returns None.

fn skip_value(&self, slice: &[u8], offset: usize) -> Option<usize>

Skip all characters up to first space symbol or end-of-input

fn skip_eq_value(&self, slice: &[u8], offset: usize) -> Option<usize>

Skip all characters up to first space symbol or end-of-input

fn check_for_duplicates( &mut self, slice: &[u8], key: Range<usize>, ) -> Result<Range<usize>, AttrError>

fn key_only( &mut self, slice: &[u8], key: Range<usize>, offset: usize, ) -> Option<Result<Attr<Range<usize>>, AttrError>>

Parameters

• slice: content of the tag, used for checking for duplicates
• key: Range of key in slice, if iterator in HTML mode
• offset: Position of error if iterator in XML mode

fn double_q( &mut self, key: Range<usize>, value: Range<usize>, ) -> Option<Result<Attr<Range<usize>>, AttrError>>

fn single_q( &mut self, key: Range<usize>, value: Range<usize>, ) -> Option<Result<Attr<Range<usize>>, AttrError>>

pub fn next( &mut self, slice: &[u8], ) -> Option<Result<Attr<Range<usize>>, AttrError>>

Trait Implementations
