Struct Cols 

pub struct Cols(pub Vec<Col>);

Sequence of columns, ordered

Tuple Fields

0: Vec<Col>

Implementations

impl Cols

pub fn empty() -> Self

pub fn is_empty(&self) -> bool

pub fn contains(&self, tbl: Col) -> bool

pub fn remove(&mut self, removed: Col)

pub fn add(&mut self, added: Col)

Add a col, preventing duplicates (may be used when the col is present to reorder)

pub fn add_set(&mut self, col_set: &[Col])

Add the columns of the set, except when they’re already present

This makes it possible to add a set while keeping the order of the previous columns, for example dysk -c disk+

pub fn remove_set(&mut self, col_set: &[Col])

pub fn cols(&self) -> &[Col]

Trait Implementations

impl Clone for Cols

fn clone(&self) -> Cols

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cols

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

Formats the value using the given formatter.

impl Default for Cols

fn default() -> Self

Returns the “default value” for a type.

impl FromStr for Cols

type Err = ParseColError

The associated error which can be returned from parsing.

fn from_str(value: &str) -> Result<Self, ParseColError>

Parses a string s to return a value of this type.

impl PartialEq for Cols

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

Tests for self and other values to be equal, and is used by ==.

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

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