Implementations

impl Value

pub fn is_null(&self) -> bool

Check if this value is null

pub fn is_bool(&self) -> bool

Check if this value is a boolean

pub fn is_integer(&self) -> bool

Check if this value is an integer

pub fn is_float(&self) -> bool

Check if this value is a float

pub fn is_string(&self) -> bool

Check if this value is a string

pub fn is_sequence(&self) -> bool

Check if this value is a sequence

pub fn is_mapping(&self) -> bool

Check if this value is a mapping

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

Get as boolean if this is a Bool

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

Get as i64 if this is an Integer

pub fn as_f64(&self) -> Option<f64>

Get as f64 if this is a Float or Integer

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

Get as str if this is a String

pub fn as_sequence(&self) -> Option<&[Value]>

Get as slice if this is a Sequence

pub fn as_mapping(&self) -> Option<&IndexMap<String, Value>>

Get as mapping if this is a Mapping

pub fn get_path(&self, path: &str) -> Result<&Value>

Get a value by path (e.g., “database.host” or “servers[0].name”)

pub fn get_path_mut(&mut self, path: &str) -> Result<&mut Value>

Get a mutable value by path

pub fn set_path(&mut self, path: &str, value: Value) -> Result<()>

Set a value at a path, creating intermediate mappings as needed

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

Returns the type name of this value

pub fn merge(&mut self, other: Value)

Merge another value into this one (deep merge per ADR-004)

Merge semantics:

• Mappings: Deep merge recursively
• Scalars: other wins (last-writer-wins)
• Sequences: other replaces entirely
• Null in other: Removes the key (handled by caller)
• Type mismatch: other wins

pub fn merged(self, other: Value) -> Value

Create a merged value from two values (non-mutating)

Trait Implementations

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Value

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

Formats the value using the given formatter.

impl Default for Value

fn default() -> Value

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Value

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Value

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

Formats the value using the given formatter.

impl From<&str> for Value

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<IndexMap<String, Value>> for Value

fn from(m: IndexMap<String, Value>) -> Self

Converts to this type from the input type.

impl From<String> for Value

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<Value> for ResolvedValue

fn from(value: Value) -> Self

Converts to this type from the input type.

impl<T: Into<Value>> From<Vec<T>> for Value

fn from(v: Vec<T>) -> Self

Converts to this type from the input type.

impl From<bool> for Value

fn from(b: bool) -> Self

Converts to this type from the input type.

impl From<f64> for Value

fn from(f: f64) -> Self

Converts to this type from the input type.

impl From<i32> for Value

fn from(i: i32) -> Self

Converts to this type from the input type.

impl From<i64> for Value

fn from(i: i64) -> Self

Converts to this type from the input type.

impl PartialEq for Value

fn eq(&self, other: &Value) -> 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.

impl Serialize for Value

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
