Struct SynthUnion 

pub struct SynthUnion {
    pub variants: Vec<SynthType>,
}

A structural union of types

Unlike schema unions, these are anonymous/structural and don’t have named variants.

Fields

variants: Vec<SynthType>

The variant types in this union

Invariants:

• At least 2 elements
• No SynthType::Union elements (flattened)
• No duplicates

Implementations

impl SynthUnion

pub fn from_variants(variants: impl IntoIterator<Item = SynthType>) -> SynthType

Create a union from variants, normalizing as needed

This function:

• Flattens nested unions
• Removes duplicates
• Returns single type if only one variant remains
• Returns Never for empty input

Trait Implementations

impl Clone for SynthUnion

fn clone(&self) -> SynthUnion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SynthUnion

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

Formats the value using the given formatter.

impl Display for SynthUnion

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

Formats the value using the given formatter.

impl PartialEq for SynthUnion

fn eq(&self, other: &SynthUnion) -> 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.
