Trait pwhash::FindNul
[−]
[src]
pub trait FindNul {
fn nul_terminated_subslice(&self) -> &[u8];
}A trait for extracting a NUL-terminated subslice from a slice.
The original Unix hashing functions expect passwords to be NUL-terminated C strings. This allows values which can't be represented by Rust strings, which are constrained to be UTF-8. On the other hand, Rust strings can contain NUL bytes, and C strings can't.
For maximum flexibility, hashing functions in this crate accept both strings and raw byte vectors as password input. This trait can be used to ensure that any input value will be truncated at the first NUL byte.
Required Methods
fn nul_terminated_subslice(&self) -> &[u8]
Subslice extraction function.
Given a slice, find and return the subslice before the first NUL byte, or the original slice if no NUL byte is found. Before searching, the slice is converted into a byte slice, if necessary. The returned slice also consists of raw bytes.
