Attributes that are "metadata" related. These might change one of the materialized views.
Methods from __Deref<Target = String>
pub fn as_str(&self) -> &str
1.7.0[src]
Extracts a string slice containing the entire string.
Examples
Basic usage:
let s = String::from("foo"); assert_eq!("foo", s.as_str());
pub fn capacity(&self) -> usize
1.0.0[src]
Returns this String
's capacity, in bytes.
Examples
Basic usage:
let s = String::with_capacity(10); assert!(s.capacity() >= 10);
pub fn as_bytes(&self) -> &[u8]
1.0.0[src]
Returns a byte slice of this String
's contents.
The inverse of this method is from_utf8
.
Examples
Basic usage:
let s = String::from("hello"); assert_eq!(&[104, 101, 108, 108, 111], s.as_bytes());
pub fn len(&self) -> usize
1.0.0[src]
Returns the length of this String
, in bytes.
Examples
Basic usage:
let a = String::from("foo"); assert_eq!(a.len(), 3);
pub fn is_empty(&self) -> bool
1.0.0[src]
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());
