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 floor(self) -> u16

The narrowest a column of this kind reads at, in ch, when it declares nothing narrower.

A date is ten characters in the form every host writes, and a number cut short is a different number, so the kinds that cannot truncate floor at what they hold. Prose and identifiers wrap or break, so theirs is only enough to be recognisable.

pub const fn holds_minimum(self) -> bool

Whether a column of this kind keeps its minimum rather than truncating when it is essential and room runs out.

A control, a figure, a date or a state cut short is wrong rather than short. Prose and identifiers end in an ellipsis and stay what they were.

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.
