Implementations

impl DataType

pub fn map<__SHRINKWRAP_T, __SHRINKWRAP_F: FnMut(String) -> __SHRINKWRAP_T>(
    self,
    f: __SHRINKWRAP_F
) -> __SHRINKWRAP_T

Map a function over the wrapped value, consuming it in the process.

pub fn map_ref<__SHRINKWRAP_T, __SHRINKWRAP_F: FnMut(&String) -> __SHRINKWRAP_T>(
    &self,
    f: __SHRINKWRAP_F
) -> __SHRINKWRAP_T

Map a function over the wrapped value without consuming it.

impl DataType

pub fn valid(&self) -> Result<()>

pub fn is_array(&self) -> bool

pub fn is_generic(&self) -> bool

pub fn array_of(&self, second: &Self) -> bool

Determine if this data type is an array of the other

pub fn within_array(&self) -> Result<Self>

Get the data type the array holds

pub fn type_string(value: &Value) -> String

Take a json data value and return the type string for it, recursively going down when the type is a container type (Array or Map(Object))

pub fn array_order(&self) -> Result<i32>

Take a string description of a DataType and determine how deeply nested in arrays it is

Methods from Deref<Target = String>

pub fn as_str(&self) -> &str

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

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]

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

Returns the length of this String, in bytes, not chars or graphemes. In other words, it may not be what a human considers the length of the string.

Examples

Basic usage:

let a = String::from("foo");
assert_eq!(a.len(), 3);

let fancy_f = String::from("ƒoo");
assert_eq!(fancy_f.len(), 4);
assert_eq!(fancy_f.chars().count(), 3);

pub fn is_empty(&self) -> bool

Returns true if this String has a length of zero, and false otherwise.

Examples

Basic usage:

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

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