Struct stringbuf::StringBuf

pub struct StringBuf(_);

Methods

impl StringBuf

fn new() -> Self

fn append<'s, S: Into<&'s str>>(self, string: S) -> Self

Methods from Deref<Target=String>

fn into_bytes(self) -> Vec<u8>

Converts a String into a byte vector.

This consumes the String, so we do not need to copy its contents.

Examples

Basic usage:

let s = String::from("hello");
let bytes = s.into_bytes();

assert_eq!(&[104, 101, 108, 108, 111][..], &bytes[..]);

fn as_str(&self) -> &str

Extracts a string slice containing the entire string.

fn capacity(&self) -> usize

Returns this String's capacity, in bytes.

Examples

Basic usage:

let s = String::with_capacity(10);

assert!(s.capacity() >= 10);

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

Returns a byte slice of this String's contents.

Examples

Basic usage:

let s = String::from("hello");

assert_eq!(&[104, 101, 108, 108, 111], s.as_bytes());

fn len(&self) -> usize

Returns the length of this String, in bytes.

Examples

Basic usage:

let a = String::from("foo");

assert_eq!(a.len(), 3);

fn is_empty(&self) -> bool

Returns true if this String has a length of zero.

Returns false otherwise.

Examples

Basic usage:

let mut v = String::new();
assert!(v.is_empty());

v.push('a');
assert!(!v.is_empty());

fn into_boxed_str(self) -> Box<str>

Converts this String into a Box<str>.

This will drop any excess capacity.

Examples

Basic usage:

let s = String::from("hello");

let b = s.into_boxed_str();
