Struct Column 

pub struct Column { /* private fields */ }

A column definition: a header, core ColumnOptions and an optional formatter.

use rich::{Justify, Text};
use rich_ext::table::{Column, Value};

let size = Column::new("size")
    .justify(Justify::Right)
    .format(|v| match v.as_f64() {
        Some(n) => Text::new(rich_ext::format::bytes(n as u64)),
        None => Text::new(""),
    });
assert_eq!(size.cell(&Value::Int(2048)).plain(), "2.0 kB");

Implementations

impl Column

pub fn new(header: impl Into<String>) -> Self

A left-justified column. The header is literal text, not markup.

pub fn justify(self, justify: Justify) -> Self

Justify the column’s cells.

pub fn options(self, options: ColumnOptions) -> Self

Replace every core column option (width, ratio, no_wrap, style, …).

pub fn format( self, formatter: impl Fn(&Value) -> Text + Send + Sync + 'static, ) -> Self

Display values through formatter instead of Value::to_text. Aggregates other than counts are formatted the same way.

pub fn header(&self) -> &str

The header text.

pub fn column_options(&self) -> &ColumnOptions

The core column options.

pub fn cell(&self, value: &Value) -> Text

A value as this column displays it.

Trait Implementations

impl Clone for Column

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Column

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

Formats the value using the given formatter.
