Struct Constraint

pub struct Constraint {
    pub min: Size,
    pub max: Size,
}

Rendering constraint.

Fields

min: Size

Minimum space the element can take.

max: Size

Maximum space the element can take.

Implementations

impl Constraint

pub const UNBOUNDED: Constraint

Can satisfy any size of object.

pub fn new(min: Size, max: Size) -> Constraint

Create a new constraint.

pub fn max(max: Size) -> Constraint

A constraint with only a maximum size.

pub fn tight(cols: usize) -> Constraint

A constraint that can only be satisfied by a single column size. The rows are unconstrained.

pub fn from_env() -> Option<Constraint>

Create a constraint from the terminal environment. Returns None if the output device is not a terminal.

Trait Implementations

impl Clone for Constraint

fn clone(&self) -> Constraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Constraint

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

Formats the value using the given formatter.

impl Default for Constraint

fn default() -> Constraint

Returns the “default value” for a type.

impl PartialEq for Constraint

fn eq(&self, other: &Constraint) -> 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 Copy for Constraint

impl Eq for Constraint

impl StructuralPartialEq for Constraint
