Enum Expr 

pub enum Expr {
    Px(f32),
    Pct(f32),
    Min(Vec<Expr>),
    Max(Vec<Expr>),
    Clamp(Box<Expr>, Box<Expr>, Box<Expr>),
}

A parsed expression: lengths in logical px, percentages as fractions.

Variants

Px(f32)

Pct(f32)

A fraction of the room ("50%" is Pct(0.5)).

Min(Vec<Expr>)

Max(Vec<Expr>)

Clamp(Box<Expr>, Box<Expr>, Box<Expr>)

clamp(min, target, max).

Implementations

impl Expr

pub fn resolve(&self, room: f32) -> f32

The expression in logical px of room px, never below zero.

pub fn relative(&self) -> bool

Whether the value depends on the room: a percentage anywhere in it.

Trait Implementations

impl Clone for Expr

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Expr

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

Formats the value using the given formatter.

impl Display for Expr

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

Formats the value using the given formatter.

impl Eq for Expr

Structural equality and hashing by the numbers’ bits: what the table finds an entry by, so data and prefix code find theirs without being spelled out first.

impl Hash for Expr

fn hash<H: Hasher>(&self, h: &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 Expr

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
