Implementations
impl Value

impl Value
[src]pub fn get<I>(&self, index: I) -> Option<&Value> where
I: Index,
[src]
pub fn get<I>(&self, index: I) -> Option<&Value> where
I: Index,
[src]Index into a YAML sequence or map. A string index can be used to access a value in a map, and a usize index can be used to access an element of an sequence.
Returns None
if the type of self
does not match the type of the
index, for example if the index is a string and self
is a sequence or
a number. Also returns None
if the given key does not exist in the map
or the given index is not within the bounds of the sequence.
let object: Value = yaml(r#"{ A: 65, B: 66, C: 67 }"#); let x = object.get("A").unwrap(); assert_eq!(x, 65); let sequence: Value = yaml(r#"[ "A", "B", "C" ]"#); let x = sequence.get(2).unwrap(); assert_eq!(x, &Value::String("C".into())); assert_eq!(sequence.get("A"), None);
Square brackets can also be used to index into a value in a more concise
way. This returns Value::Null
in cases where get
would have returned
None
.
let object = yaml(r#" --- A: [a, á, à] B: [b, b́] C: [c, ć, ć̣, ḉ] 42: true "#); assert_eq!(object["B"][0], Value::String("b".into())); assert_eq!(object[Value::String("D".into())], Value::Null); assert_eq!(object["D"], Value::Null); assert_eq!(object[0]["x"]["y"]["z"], Value::Null); assert_eq!(object[42], Value::Bool(true));
pub fn get_mut<I>(&mut self, index: I) -> Option<&mut Value> where
I: Index,
[src]
pub fn get_mut<I>(&mut self, index: I) -> Option<&mut Value> where

Returns None

[src]
impl<I> Index<I> for Value where
I: Index,
[src]pub fn index(&self, index: I) -> &Value
[src]
pub fn index(&self, index: I) -> &Value
[src]Index into a serde_yaml::Value
using the syntax value[0]
or
value["k"]
.
Returns Value::Null
if the type of self
does not match the type of
the index, for example if the index is a string and self
is a sequence
or a number. Also returns Value::Null
if the given key does not exist
in the map or the given index is not within the bounds of the sequence.
For retrieving deeply nested values, you should have a look at the
Value::pointer
method.
Examples
let data = yaml(r#"{ x: { y: [z, zz] } }"#); assert_eq!(data["x"]["y"], yaml(r#"["z", "zz"]"#)); assert_eq!(data["x"]["y"][0], yaml(r#""z""#)); assert_eq!(data["a"], yaml(r#"null"#)); // returns null for undefined values assert_eq!(data["a"]["b"], yaml(r#"null"#)); // does not panic

[src]
impl<I> IndexMut<I> for Value where
I: Index,
[src]pub fn index_mut(&mut self, index: I) -> &mut Value
[src]
pub fn index_mut(&mut self, index: I) -> &mut Value
[src]Write into a serde_yaml::Value
using the syntax value[0] = ...
or
value["k"] = ...
.
If the index is a number, the value must be a sequence of length bigger than the index. Indexing into a value that is not a sequence or a sequence that is too small will panic.
If the index is a string, the value must be an object or null which is treated like an empty object. If the key is not already present in the object, it will be inserted with a value of null. Indexing into a value that is neither an object nor null will panic.
Examples
let mut data = yaml(r#"{x: 0}"#); // replace an existing key data["x"] = yaml(r#"1"#); // insert a new key data["y"] = yaml(r#"[false, false, false]"#); // replace a value in a sequence data["y"][0] = yaml(r#"true"#); // inserted a deeply nested key data["a"]["b"]["c"]["d"] = yaml(r#"true"#); println!("{:?}", data);
