Trait SampleString

pub trait SampleString {
    // Required method
    fn append_string<R: Rng + ?Sized>(
        &self,
        rng: &mut R,
        string: &mut String,
        len: usize,
    );

    // Provided method
    fn sample_string<R: Rng + ?Sized>(&self, rng: &mut R, len: usize) -> String { ... }

Sample or extend a String

Helper methods to extend a String or sample a new String.

Required Methods

fn append_string<R: Rng + ?Sized>( &self, rng: &mut R, string: &mut String, len: usize, )

Append len random chars to string

Note: implementations may leave string with excess capacity. If this is undesirable, consider calling String::shrink_to_fit after this method.

Provided Methods

fn sample_string<R: Rng + ?Sized>(&self, rng: &mut R, len: usize) -> String

Generate a String of len random chars

Note: implementations may leave the string with excess capacity. If this is undesirable, consider calling String::shrink_to_fit after this method.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
