Implementations

impl FieldRange

pub const fn default() -> Self

pub fn from_list(list: &str) -> Result<Vec<FieldRange>, FieldError>

Parse a comma separated list of fields and merge any overlaps

pub fn from_header_list(
    list: &[Regex],
    header: &[u8],
    delim: &RegexOrStr<'_>,
    header_is_regex: bool
) -> Result<Vec<FieldRange>, FieldError>

Get the indices of the headers that match any of the provided regex’s.

pub fn post_process_ranges(ranges: &mut Vec<FieldRange>)

Sort and merge overlaps in a set of Vec<FieldRange>.

pub fn contains(&self, value: usize) -> bool

Test if a value is contained in this range

Trait Implementations
