Struct untrusted::no_panic::Slice

source ·
pub struct Slice<'a> {
    bytes: &'a [u8],
}
Expand description

A wrapper around a slice that exposes no functions that can panic.

Intentionally avoids implementing Debug, Eq, and PartialEq to avoid creating a side channel that would leak information about the value.
