Std.Random.secureBytes

fn

This is a callable function.

What it does

Cryptographically strong bytes from the operating system.

This is separate from Generator: deterministic sequences are useful for

tests and simulation, while secrets and protocol nonces must not be

reproducible. Failure is returned and never replaced with clock-seeded

output. Requests above one mebibyte are refused at the runtime boundary.

Read the signature

• The text after the name is the type checked by Pudu.
• Read arrows from left to right: inputs come first, and the final type is returned.
• Names inside [ ] are type arguments, such as the item type held by a collection.
• Result makes success and recoverable failure part of the function's type.
