Struct simble::Printable

pub struct Printable(_);

Symbol that can be borrowed directly as a &str or &[u8]. Comparison is supported, but order is unspecified and must not be relied on (for predictable sorting, use Lexical).

Methods

impl Printable

pub fn len(self) -> usize

Return the length of this symbol.

pub fn into_bytes(self) -> [u8; 8]

Convert a Printable into a byte array. The result is right-padded with NUL bytes.

pub fn as_ptr(&self) -> *const u8

Obtain a pointer to the first byte.

pub fn as_bytes(&self) -> &[u8]

Borrow as a byte slice.

pub fn as_str(&self) -> &str

Borrow as a &str.

Important traits for Bytes

impl Iterator for Bytes type Item = u8;

pub fn bytes(self) -> Bytes

Obtain an iterator over the bytes.

pub fn to_lexical(self) -> Lexical

Convert to a lexically-sortable symbol.
