Struct Inference 

pub struct Inference { /* private fields */ }

Every column’s inferred type, from Inferrer::infer.

Implementations

impl Inference

pub fn columns(&self) -> &[ColumnInference]

One entry per column, in order.

pub fn schema(&self) -> Schema

The schema these types describe: a field per column, nullable when any cell was null.

pub fn apply(&self, rows: &mut Rows)

Convert rows’ cells to their columns’ types and attach schema: null tokens become Value::Null, integer columns Value::Int, float columns Value::Float. Booleans, dates and timestamps stay as written (Value has no variant for them) but are typed in the schema. A cell that does not parse as its column’s (overridden) type is left as it was.

impl Inference

pub fn to_table(&self) -> Table

The table this renders as: column, type, parsed, nulls.

Trait Implementations

impl Clone for Inference

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 Inference

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

Formats the value using the given formatter.

impl Eq for Inference

impl PartialEq for Inference

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

Equality operator ==.

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

Inequality operator !=.

impl Renderable for Inference

A table of column, type and evidence.

fn rich_render( &self, console: &Console, options: &ConsoleOptions, ) -> Vec<Segment>

fn measure(&self, console: &Console, options: &ConsoleOptions) -> Measurement

The (minimum, maximum) cell width this renderable wants. The default assumes the renderable fills the available width (e.g. Panel, Table); Text overrides it with its content width so the top-level print path can shrink to fit. Port of __rich_measure__ / Measurement.get.

fn fit_to_measurement(&self) -> bool

Whether a top-level Console::print shrinks this renderable to its measured width. Upstream renders every top-level renderable at the full console width, so the default is false; an extension may opt in.

fn vertical(&self) -> Option<VerticalAlign>

The vertical alignment a Table cell holding this renderable uses in place of its column’s. Upstream reads getattr(renderable, "vertical", None); Align sets it.
