Struct EnumTableBuilder

pub struct EnumTableBuilder<K: Enumable, V, const N: usize> { /* private fields */ }

A builder for creating an EnumTable with a specified number of elements.

EnumTableBuilder allows for the incremental construction of an EnumTable by pushing elements one by one and then building the final table.

Implementations

impl<K: Enumable, V, const N: usize> EnumTableBuilder<K, V, N>

pub const fn new() -> Self

Creates a new EnumTableBuilder with an uninitialized table.

Returns

A new instance of EnumTableBuilder.

pub const fn push(&mut self, variant: &K, value: V)

Pushes a new element into the builder.

Arguments

• variant - A reference to an enumeration variant.
• value - The value to associate with the variant.

pub const fn build(self) -> [(Discriminant<K>, V); N]

Builds the table from the pushed elements.

Returns

An array of tuples where each tuple contains a discriminant of an enumeration variant and its associated value.

pub const fn build_to(self) -> EnumTable<K, V, N>

Builds the EnumTable from the pushed elements.

Returns

An EnumTable containing the elements pushed into the builder.

pub const fn len(&self) -> usize

Returns the number of elements the builder is expected to hold.

Returns

The number of elements N.

pub const fn is_empty(&self) -> bool

Returns false as the builder is expected to be filled completely.

Returns

Always returns false.

fn default() -> Self

Returns the “default value” for a type.
