Enum Value 

pub enum Value {
    Null,
    Int(i64),
    Float(f64),
    Str(String),
    Text(Text),
}

A typed table cell.

The type drives sorting (sort) and aggregation (group); the column’s formatter (or Value::to_text) drives display.

Variants

Null

No value. Renders empty and sorts last.

Int(i64)

An integer.

Float(f64)

A floating-point number.

Str(String)

Literal text (never parsed as markup).

Text(Text)

Styled text; sorts and groups by its plain string.

Implementations

impl Value

pub fn is_empty(&self) -> bool

Whether the value is Null or has an empty string.

pub fn as_f64(&self) -> Option<f64>

The value as a number, for Int and Float only.

pub fn plain(&self) -> String

The plain display string: empty for Null, Display for numbers.

pub fn to_text(&self) -> Text

The default display: plain as literal text, or the Text itself.

Trait Implementations

impl Clone for Value

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 Value

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

Formats the value using the given formatter.

impl Default for Value

fn default() -> Self

Returns the “default value” for a type.

impl From<&str> for Value

fn from(s: &str) -> Self

Converts to this type from the input type.

impl<T: Into<Value>> From<Option<T>> for Value

fn from(v: Option<T>) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<Text> for Value

fn from(t: Text) -> Self

Converts to this type from the input type.

impl From<f64> for Value

fn from(f: f64) -> Self

Converts to this type from the input type.

impl From<i8> for Value

fn from(n: i8) -> Self

Converts to this type from the input type.

impl From<i16> for Value

fn from(n: i16) -> Self

Converts to this type from the input type.

impl From<i32> for Value

fn from(n: i32) -> Self

Converts to this type from the input type.

impl From<i64> for Value

fn from(n: i64) -> Self

Converts to this type from the input type.

impl From<isize> for Value

fn from(n: isize) -> Self

Converts to this type from the input type.

impl From<u8> for Value

fn from(n: u8) -> Self

Converts to this type from the input type.

impl From<u16> for Value

fn from(n: u16) -> Self

Converts to this type from the input type.

impl From<u32> for Value

fn from(n: u32) -> Self

Converts to this type from the input type.

impl From<u64> for Value

fn from(n: u64) -> Self

Converts to this type from the input type.

impl From<usize> for Value

fn from(n: usize) -> Self

Converts to this type from the input type.

impl PartialEq for Value

Values compare by variant and content (floats bit for bit). A Value::Text never equals anything, itself included, because its base style cannot be compared: StreamingTable treats writing one as a change. Prefer Value::Str for data.

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

Equality operator ==.

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

Inequality operator !=.
