Struct Proposal 

pub struct Proposal {
    pub width: Option<f64>,
    pub height: Option<f64>,
}

The layout proposal: None = unconstrained on that axis (§7.2).

Fields

width: Option<f64>

height: Option<f64>

Implementations

impl Proposal

pub const UNCONSTRAINED: Proposal

pub const fn new(width: Option<f64>, height: Option<f64>) -> Self

pub const fn exact(size: Size) -> Self

pub fn cache_key(&self) -> (u64, u64)

Quantized key for the measurement cache (§7.4): tenth-of-a-point buckets.

Trait Implementations

impl Clone for Proposal

fn clone(&self) -> Proposal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Proposal

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

Formats the value using the given formatter.

impl Default for Proposal

fn default() -> Proposal

Returns the “default value” for a type.

impl PartialEq for Proposal

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