Struct Constraints 

pub struct Constraints {
    pub min_width: Option<u32>,
    pub max_width: Option<u32>,
    pub min_height: Option<u32>,
    pub max_height: Option<u32>,
    pub width_pct: Option<u8>,
    pub height_pct: Option<u8>,
}

Size constraints for layout computation.

All fields are optional. Unset constraints are unconstrained. Use the builder methods to set individual bounds in a fluent style.

Example

use slt::Constraints;

let c = Constraints::default().min_w(10).max_w(40);

Fields

min_width: Option<u32>

Minimum width in terminal columns, if any.

max_width: Option<u32>

Maximum width in terminal columns, if any.

min_height: Option<u32>

Minimum height in terminal rows, if any.

max_height: Option<u32>

Maximum height in terminal rows, if any.

width_pct: Option<u8>

Width as a percentage (1-100) of the parent container.

height_pct: Option<u8>

Height as a percentage (1-100) of the parent container.

Implementations

impl Constraints

pub const fn min_w(self, min_width: u32) -> Self

Set the minimum width constraint.

pub const fn max_w(self, max_width: u32) -> Self

Set the maximum width constraint.

pub const fn min_h(self, min_height: u32) -> Self

Set the minimum height constraint.

pub const fn max_h(self, max_height: u32) -> Self

Set the maximum height constraint.

pub const fn w_pct(self, pct: u8) -> Self

Set width as a percentage (1-100) of the parent container.

pub const fn h_pct(self, pct: u8) -> Self

Set height as a percentage (1-100) of the parent container.

Trait Implementations

impl Clone for Constraints

fn clone(&self) -> Constraints

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Constraints

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

Formats the value using the given formatter.

impl Default for Constraints

fn default() -> Constraints

Returns the “default value” for a type.

impl Hash for Constraints

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 Constraints

fn eq(&self, other: &Constraints) -> 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 Constraints

impl Eq for Constraints

impl StructuralPartialEq for Constraints
