Struct YsonValue 

pub struct YsonValue {
    pub attributes: Option<BTreeMap<Vec<u8>, YsonValue>>,
    pub node: YsonNode,
}

Represents a complete YSON value, including its optional attributes and data node.

Fields

attributes: Option<BTreeMap<Vec<u8>, YsonValue>>

Optional attributes associated with this value. In YSON, attributes are stored as a map of byte strings to other YSON values.

node: YsonNode

The data content of this YSON node.

Implementations

impl YsonValue

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

Attempts to interpret the node as a UTF-8 string. Returns None if the node is not a string or if the bytes are not valid UTF-8.

pub fn as_i64(&self) -> Option<i64>

Attempts to interpret the node as a 64-bit signed integer. Returns None if the node is not an Int64.

pub fn attr(&self, key: &str) -> Option<&YsonValue>

Retrieves an attribute by its string key. Returns None if attributes are missing or the key is not found.

Trait Implementations

impl Clone for YsonValue

fn clone(&self) -> YsonValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for YsonValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for YsonValue

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> Index<&'a str> for YsonValue

fn index(&self, key: &'a str) -> &Self::Output

Provides convenient access to map elements or attributes using index notation.

Panics

Panics if the key is not found or if the value is not a map.

Examples

use ytsaurus_yson::{YsonValue, from_slice, YsonFormat};

let input = b"<status=\"ok\">{id=1u}";
let value: YsonValue = from_slice(input, YsonFormat::Text).unwrap();

// Access an attribute with '@' prefix
assert_eq!(value["@status"].as_str(), Some("ok"));

// Access a map field directly
// Note: value["id"] would work if it were a map

type Output = YsonValue

The returned type after indexing.

impl PartialEq for YsonValue

fn eq(&self, other: &YsonValue) -> bool

Equality operator ==.

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

Inequality operator !=.

impl Serialize for YsonValue

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Round-trips through crate::to_vec/crate::from_slice.

Note that maps are stored in a BTreeMap, so keys come back out in sorted order rather than in the order they appeared in the input. The round-trip therefore preserves the value, not the exact byte layout.
