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: &RegexOrString,
    header_is_regex: bool,
    allow_missing: 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

pub fn overlap(&self, other: &Self) -> bool

Test if two ranges overlap

pub fn exclude(
    fields: Vec<FieldRange>,
    exclude: Vec<FieldRange>
) -> Vec<FieldRange>

Remove ranges in exclude from fields.

This assumes both fields and exclude are in ascending order by low value.

Trait Implementations

impl Clone for FieldRange

fn clone(&self) -> FieldRange

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FieldRange

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromStr for FieldRange

fn from_str(s: &str) -> Result<FieldRange, FieldError>

Convert a str into a FieldRange

type Err = FieldError

The associated error which can be returned from parsing.

impl Ord for FieldRange

fn cmp(&self, other: &FieldRange) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<FieldRange> for FieldRange

fn eq(&self, other: &FieldRange) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<FieldRange> for FieldRange

fn partial_cmp(&self, other: &FieldRange) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
