Enum ColumnKind 

#[non_exhaustive]
pub enum ColumnKind {
    Text,
    Identifier,
    Date,
    Number,
    Code,
    Status,
    Actions,
}

What a column holds.

wiki table-model: the kind is what carries a column’s look, and four of the reference table’s six rules were per kind rather than per table. A description states what the column is; each renderer decides what that looks like in its host, from the facts below rather than from the name.

#[non_exhaustive], Width’s reasoning.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Text

Prose. Wraps. What a column is when it says nothing else.

Identifier

A name a machine made: a fingerprint, a hash, a slug. Monospace, and breaks mid-string rather than widening the table.

Date

A point in time. Never wraps, so a date cannot print over its neighbour, and its figures line up down the column.

Number

A quantity. Figures line up and the column aligns to its end, so magnitudes compare by length.

Code

Source text, one row per line. Monospace and never wrapped. A table holding one is read as code, so its rows are not striped or spaced as records.

Status

A state the row is in, drawn as a chip rather than as coloured text.

Actions

The row’s controls. Aligns to its end and shrinks to what it holds.

Implementations

impl ColumnKind

pub const fn aligns_end(self) -> bool

Whether the column aligns to its end rather than its start.

pub const fn wraps(self) -> bool

Whether the column’s text may wrap onto a second line.

An identifier wraps by breaking mid-string, which is still a wrap: the alternative is a fingerprint forcing the table wider than its pane.

pub const fn monospace(self) -> bool

Whether the column is set in the monospace face.

pub const fn tabular(self) -> bool

Whether figures in the column take equal widths.
