Methods
impl Value
[src]
fn get<I: Index>(&self, index: I) -> Option<&Value>
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));
fn is_null(&self) -> bool
Returns true if the Value
is a Null. Returns false otherwise.
For any Value on which is_null
returns true, as_null
is guaranteed
to return Some(())
.
let v: Value = serde_yaml::from_str("null").unwrap(); assert!(v.is_null());
let v: Value = serde_yaml::from_str("false").unwrap(); assert!(!v.is_null());
fn as_null(&self) -> Option<()>
If the Value
is a Null, returns (). Returns None otherwise.
let v: Value = serde_yaml::from_str("null").unwrap(); assert_eq!(v.as_null(), Some(()));
let v: Value = serde_yaml::from_str("false").unwrap(); assert_eq!(v.as_null(), None);
fn is_bool(&self) -> bool
Returns true if the Value
is a Boolean. Returns false otherwise.
For any Value on which is_boolean
returns true, as_bool
is
guaranteed to return the boolean value.
let v: Value = serde_yaml::from_str("true").unwrap(); assert!(v.is_bool());
let v: Value = serde_yaml::from_str("42").unwrap(); assert!(!v.is_bool());
fn as_bool(&self) -> Option<bool>
If the Value
is a Boolean, returns the associated bool. Returns None
otherwise.
let v: Value = serde_yaml::from_str("true").unwrap(); assert_eq!(v.as_bool(), Some(true));
let v: Value = serde_yaml::from_str("42").unwrap(); assert_eq!(v.as_bool(), None);
fn is_number(&self) -> bool
Returns true if the Value
is a Number. Returns false otherwise.
let v: Value = serde_yaml::from_str("5").unwrap(); assert!(v.is_number());
let v: Value = serde_yaml::from_str("true").unwrap(); assert!(!v.is_number());
fn is_i64(&self) -> bool
Returns true if the Value
is an integer between i64::MIN
and
i64::MAX
.
For any Value on which is_i64
returns true, as_i64
is guaranteed to
return the integer value.
let v: Value = serde_yaml::from_str("1337").unwrap(); assert!(v.is_i64());
let v: Value = serde_yaml::from_str("null").unwrap(); assert!(!v.is_i64());
fn as_i64(&self) -> Option<i64>
If the Value
is an integer, represent it as i64 if possible. Returns
None otherwise.
let v: Value = serde_yaml::from_str("1337").unwrap(); assert_eq!(v.as_i64(), Some(1337));
let v: Value = serde_yaml::from_str("false").unwrap(); assert_eq!(v.as_i64(), None);
fn is_u64(&self) -> bool
Returns true if the Value
is an integer between u64::MIN
and
u64::MAX
.
For any Value on which is_u64
returns true, as_u64
is guaranteed to
return the integer value.
let v: Value = serde_yaml::from_str("1337").unwrap(); assert!(v.is_u64());
let v: Value = serde_yaml::from_str("null").unwrap(); assert!(!v.is_u64());
fn as_u64(&self) -> Option<u64>
If the Value
is an integer, represent it as i64 if possible. Returns
None otherwise.
let v: Value = serde_yaml::from_str("1337").unwrap(); assert_eq!(v.as_u64(), Some(1337));
let v: Value = serde_yaml::from_str("false").unwrap(); assert_eq!(v.as_u64(), None);
fn is_f64(&self) -> bool
Returns true if the Value
is a number that can be represented by f64.
For any Value on which is_f64
returns true, as_f64
is guaranteed to
return the floating point value.
Currently this function returns true if and only if both is_i64
and
is_u64
return false but this is not a guarantee in the future.
let v: Value = serde_yaml::from_str("256.01").unwrap(); assert!(v.is_f64());
let v: Value = serde_yaml::from_str("true").unwrap(); assert!(!v.is_f64());
fn as_f64(&self) -> Option<f64>
If the Value
is a number, represent it as f64 if possible. Returns
None otherwise.
let v: Value = serde_yaml::from_str("13.37").unwrap(); assert_eq!(v.as_f64(), Some(13.37));
let v: Value = serde_yaml::from_str("false").unwrap(); assert_eq!(v.as_f64(), None);
fn is_string(&self) -> bool
Returns true if the Value
is a String. Returns false otherwise.
For any Value on which is_string
returns true, as_str
is guaranteed
to return the string slice.
let v: Value = serde_yaml::from_str("'lorem ipsum'").unwrap(); assert!(v.is_string());
let v: Value = serde_yaml::from_str("42").unwrap(); assert!(!v.is_string());
fn as_str(&self) -> Option<&str>
If the Value
is a String, returns the associated str. Returns None
otherwise.
let v: Value = serde_yaml::from_str("'lorem ipsum'").unwrap(); assert_eq!(v.as_str(), Some("lorem ipsum"));
let v: Value = serde_yaml::from_str("false").unwrap(); assert_eq!(v.as_str(), None);
fn is_sequence(&self) -> bool
Returns true if the Value
is a sequence. Returns false otherwise.
let v: Value = serde_yaml::from_str("[1, 2, 3]").unwrap(); assert!(v.is_sequence());
let v: Value = serde_yaml::from_str("true").unwrap(); assert!(!v.is_sequence());
fn as_sequence(&self) -> Option<&Sequence>
If the Value
is a sequence, return a reference to it if possible.
Returns None otherwise.
let v: Value = serde_yaml::from_str("[1, 2]").unwrap(); assert_eq!(v.as_sequence(), Some(&vec![Value::Number(Number::from(1)), Value::Number(Number::from(2))]));
let v: Value = serde_yaml::from_str("false").unwrap(); assert_eq!(v.as_sequence(), None);
fn as_sequence_mut(&mut self) -> Option<&mut Sequence>
If the Value
is a sequence, return a mutable reference to it if
possible. Returns None otherwise.
let mut v: Value = serde_yaml::from_str("[1]").unwrap(); let s = v.as_sequence_mut().unwrap(); s.push(Value::Number(Number::from(2))); assert_eq!(s, &vec![Value::Number(Number::from(1)), Value::Number(Number::from(2))]);
let mut v: Value = serde_yaml::from_str("false").unwrap(); assert_eq!(v.as_sequence_mut(), None);
fn is_mapping(&self) -> bool
Returns true if the Value
is a mapping. Returns false otherwise.
let v: Value = serde_yaml::from_str("a: 42").unwrap(); assert!(v.is_mapping());
let v: Value = serde_yaml::from_str("true").unwrap(); assert!(!v.is_mapping());
fn as_mapping(&self) -> Option<&Mapping>
If the Value
is a mapping, return a reference to it if possible.
Returns None otherwise.
let v: Value = serde_yaml::from_str("a: 42").unwrap(); let mut expected = Mapping::new(); expected.insert(Value::String("a".into()),Value::Number(Number::from(42))); assert_eq!(v.as_mapping(), Some(&expected));
let v: Value = serde_yaml::from_str("false").unwrap(); assert_eq!(v.as_mapping(), None);
fn as_mapping_mut(&mut self) -> Option<&mut Mapping>
If the Value
is a mapping, return a reference to it if possible.
Returns None otherwise.
let mut v: Value = serde_yaml::from_str("a: 42").unwrap(); let m = v.as_mapping_mut().unwrap(); m.insert(Value::String("b".into()),Value::Number(Number::from(21))); let mut expected = Mapping::new(); expected.insert(Value::String("a".into()),Value::Number(Number::from(42))); expected.insert(Value::String("b".into()),Value::Number(Number::from(21))); assert_eq!(m, &expected);
let mut v: Value = serde_yaml::from_str("false").unwrap(); assert_eq!(v.as_mapping_mut(), None);
Trait Implementations
impl<I> Index<I> for Value where
I: Index,
[src]
I: Index,
type Output = Value
The returned type after indexing
fn index(&self, index: I) -> &Value
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
impl<I> IndexMut<I> for Value where
I: Index,
[src]
I: Index,
fn index_mut(&mut self, index: I) -> &mut Value
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);
