Enum Width 

pub enum Width {
    Fixed(usize),
    Bounded {
        min: Option<usize>,
        max: Option<usize>,
    },
    Fill,
    Fraction(usize),
}

Specifies how a column determines its width.

Variants

Fixed(usize)

Fixed width in display columns.

Bounded

Width calculated from content, constrained by optional min/max bounds.

Fields

min: Option<usize>

Minimum width (defaults to 0 if not specified).

max: Option<usize>

Maximum width (unlimited if not specified).

Fill

Expand to fill all remaining space. Multiple Fill columns share remaining space equally.

Fraction(usize)

Proportional: takes n parts of the remaining space. Fraction(2) gets twice the space of Fraction(1) or Fill.

Implementations

impl Width

pub fn fixed(width: usize) -> Self

Create a fixed-width column.

pub fn bounded(min: usize, max: usize) -> Self

Create a bounded-width column with both min and max.

pub fn min(min: usize) -> Self

Create a column with only a minimum width.

pub fn max(max: usize) -> Self

Create a column with only a maximum width.

pub fn fill() -> Self

Create a fill column that expands to remaining space.

pub fn fraction(n: usize) -> Self

Create a fractional width column. Fraction(2) gets twice the space of Fraction(1) or Fill.

Trait Implementations

impl Clone for Width

fn clone(&self) -> Width

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Width

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

Formats the value using the given formatter.

impl Default for Width

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Width

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Width

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Width

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Width

impl StructuralPartialEq for Width
