Enum Constraint 

pub enum Constraint {
    Min(u16),
    Max(u16),
    Length(u16),
    Percentage(u16),
    Ratio(u32, u32),
    Fill(u16),
}

A size constraint for layout elements.

Variants

Min(u16)

Minimum size in terminal columns or rows.

Max(u16)

Maximum size in terminal columns or rows.

Length(u16)

Exact size in terminal columns or rows.

Percentage(u16)

Percentage of the total available space.

Ratio(u32, u32)

Proportional fraction of the total space (numerator, denominator).

Fill(u16)

Grows to fill remaining space with the given priority.

Trait Implementations

impl AsRef<Constraint> for Constraint

fn as_ref(&self) -> &Self

Converts this type into a shared reference of the (usually inferred) input type.

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 Copy for Constraint

impl Debug for Constraint

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

Formats the value using the given formatter.

impl Default for Constraint

fn default() -> Self

Returns the “default value” for a type.

impl Display for Constraint

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

Formats the value using the given formatter.

impl Eq for Constraint

impl From<&Constraint> for Constraint

fn from(constraint: &Self) -> Self

Converts to this type from the input type.

impl From<u16> for Constraint

fn from(length: u16) -> Self

Converts to this type from the input type.

impl Hash for Constraint

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
