Struct RandStr

pub struct RandStr<'r, const L: usize = 32>(/* private fields */);

Randon string, with fix length and given charset.

Generic Parameters

• L: The length of the string. Default is 32.

Notice: must make sure each u8 within the slice is valid single byte UTF-8 char.

If the charset is 0123456789abcdef, RandHexStr is recommended and 4~6x faster than this (when feature feat-random-fast enabled).

Implementations

impl<'r> RandStr<'r>

pub const fn with_charset_default(charset: &'r [u8]) -> Self

Create a new RandStr and generate random string with length setting by L.

impl<'r, const L: usize> RandStr<'r, L>

pub const fn with_charset(charset: &'r [u8]) -> Self

Create a new RandStr and generate random string with length setting by L.

pub const fn with_l<const NL: usize>(self) -> RandStr<'r, NL>

Set L.
