Struct EnumTypeBuilder 

pub struct EnumTypeBuilder { /* private fields */ }

Builder for constructing EnumType instances in const contexts.

This builder enables shorter derive macro output by providing a fluent API for constructing enum types with default values for optional fields.

Example

use facet_core::{EnumTypeBuilder, EnumRepr, Repr, EnumType};

const ENUM: EnumType = EnumTypeBuilder::new(EnumRepr::U8, &[])
    .repr(Repr::c())
    .build();

Implementations

impl EnumTypeBuilder

pub const fn new(enum_repr: EnumRepr, variants: &'static [Variant]) -> Self

Creates a new EnumTypeBuilder with the required fields.

Parameters

• enum_repr: The representation of the enum’s discriminant
• variants: All variants for this enum

pub const fn repr(self, repr: Repr) -> Self

Sets the representation of the enum’s data.

Defaults to Repr::c() if not called.

pub const fn build(self) -> EnumType

Builds the final EnumType instance.
