Enum HeightSpec 

#[non_exhaustive]
pub enum HeightSpec {
    Auto,
    Fixed(u32),
    Pct(u8),
    Ratio(u16, u16),
    MinMax {
        min: u32,
        max: u32,
    },
}

Height specification for a flexbox item.

Mirror of WidthSpec for the cross axis. See WidthSpec for full variant semantics, including the sentinel encoding of Self::MinMax.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Auto

Unconstrained — sizes from content and available space.

Fixed(u32)

Exact cell height.

Pct(u8)

Percentage of parent height (0..=100).

Ratio(u16, u16)

Exact integer fraction of parent (numerator, denominator).

Ratio(1, 3) produces area / 3. Floor division — for area = 80, num = 1, den = 3 → 26. A den of 0 is treated as no constraint.

MinMax

Min and/or max bounds. Sentinels: min = 0 and max = u32::MAX represent “no bound”. See WidthSpec::MinMax for full rationale.

Fields

min: u32

Minimum height. 0 means unbounded below.

max: u32

Maximum height. u32::MAX means unbounded above.

Trait Implementations

impl Clone for HeightSpec

fn clone(&self) -> HeightSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HeightSpec

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

Formats the value using the given formatter.

impl Default for HeightSpec

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for HeightSpec

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for HeightSpec

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 HeightSpec

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
