Struct fruitbasket::FruitError
[−]
[src]
pub struct FruitError { /* fields omitted */ }
Class for errors generated by fruitbasket. Dereferences to a String.
Methods from Deref<Target = String>
fn into_bytes(self) -> Vec<u8>
1.0.0
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
1.7.0
Extracts a string slice containing the entire string.
fn capacity(&self) -> usize
1.0.0
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]
1.0.0
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());
fn len(&self) -> usize
1.0.0
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
1.0.0
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>
1.4.0
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();
