Struct CodeBuilder 

pub struct CodeBuilder<R: RandomSource> { /* private fields */ }

Chainable string composer. It only joins string fragments; it has no uniqueness, retry, persistence, or denylist policy.

Implementations

impl<R: RandomSource> CodeBuilder<R>

pub fn new(rng: R) -> Self

Start a builder with the given random source.

pub fn add(self, value: impl Into<String>) -> Self

Append an arbitrary string fragment.

pub fn add_with<F: FnOnce(&mut R) -> String>(self, f: F) -> Self

Append a fragment produced from the builder’s own random source.

Language crates use this to add generated words without owning a second random source.

pub fn dash(self) -> Self

Append a - separator.

pub fn digits(self, length: usize) -> Self

Append length random decimal digits.

pub fn nums(self, length: usize) -> Self

Alias for CodeBuilder::digits.

pub fn build(self) -> String

Finalize and return the joined code string.
