Enum Property

pub enum Property<Key = String> {
    String(Key, String),
    Bytes(Key, Vec<u8>),
    Int(Key, i64),
    Uint(Key, u64),
    Double(Key, f64),
    Bool(Key, bool),
    DoubleArray(Key, ArrayContent<f64>),
    IntArray(Key, ArrayContent<i64>),
    UintArray(Key, ArrayContent<u64>),
    StringList(Key, Vec<String>),
}

A named property. Each of the fields consists of (name, value).

Key is the type of the property’s name and is typically a string. In cases where there are well known, common property names, an alternative may be used to reduce copies of the name.

Variants

String(Key, String)

The value is a string.

Bytes(Key, Vec<u8>)

The value is a bytes vector.

Int(Key, i64)

The value is an integer.

Uint(Key, u64)

The value is an unsigned integer.

Double(Key, f64)

The value is a double.

Bool(Key, bool)

The value is a boolean.

DoubleArray(Key, ArrayContent<f64>)

The value is a double array.

IntArray(Key, ArrayContent<i64>)

The value is an integer array.

UintArray(Key, ArrayContent<u64>)

The value is an unsigned integer array.

StringList(Key, Vec<String>)

The value is a list of strings.

Implementations

impl<Key> Property<Key>

pub fn int(&self) -> Option<i64>

Returns the Int value or None if the property isn’t of that type

pub fn uint(&self) -> Option<u64>

Returns the Uint value or None if the property isn’t of that type

pub fn double(&self) -> Option<f64>

Returns the Double value or None if the property isn’t of that type

pub fn boolean(&self) -> Option<bool>

Returns the Bool value or None if the property isn’t of that type

impl<Key> Property<Key>

pub fn string(&self) -> Option<&str>

Returns the String value or None if the property isn’t of that type

pub fn bytes(&self) -> Option<&[u8]>

Returns the Bytes value or None if the property isn’t of that type

pub fn double_array(&self) -> Option<&ArrayContent<f64>>

Returns the DoubleArray value or None if the property isn’t of that type

pub fn int_array(&self) -> Option<&ArrayContent<i64>>

Returns the IntArray value or None if the property isn’t of that type

pub fn uint_array(&self) -> Option<&ArrayContent<u64>>

Returns the UintArray value or None if the property isn’t of that type

pub fn string_list(&self) -> Option<&[String]>

Returns the StringList value or None if the property isn’t of that type

impl<K> Property<K>

pub fn key(&self) -> &K

Returns the key of a property

pub fn discriminant_name(&self) -> &'static str

Returns a string indicating which variant of property this is, useful for printing debug values.

pub fn number_as_int(&self) -> Option<i64>

Return a a numeric property as a signed integer. Useful for having a single function to call when a property has been passed through JSON, potentially losing its original signedness.

Note: unsigned integers larger than isize::MAX will be returned as None. If you expect values that high, consider calling Property::int() and Property::uint() directly.

impl<Key> Property<Key>

where Key: AsRef<str>,

pub fn name(&self) -> &str

Returns the key of a property.

Trait Implementations

impl<Key> Clone for Property<Key>

where Key: Clone,

fn clone(&self) -> Property<Key>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Key> Debug for Property<Key>

where Key: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<K> Display for Property<K>

where K: AsRef<str>,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<Key> PartialEq for Property<Key>

where Key: PartialEq,

fn eq(&self, other: &Property<Key>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
