Enum KeySegment 

pub enum KeySegment {
    Key(String),
    Index(usize),
    Attribute(String),
}

A segment of a configuration key path.

Key segments represent individual components of a key path:

• Key: A named field (e.g., .database.url)
• Index: An array index (e.g., .items[0])
• Attribute: An attribute name (e.g., @type)

Variants

Key(String)

A named key segment.

Index(usize)

An array index segment.

Attribute(String)

An attribute name segment.

Implementations

impl KeySegment

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

Returns the key value if this is a key segment.

pub const fn as_index(&self) -> Option<usize>

Returns the index value if this is an index segment.

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

Returns the attribute name if this is an attribute segment.

pub fn into_key(self) -> Option<String>

Consumes this segment and returns the key value if it was a key segment.

pub fn into_index(self) -> Option<usize>

Consumes this segment and returns the index value if it was an index segment.

pub fn into_attribute(self) -> Option<String>

Consumes this segment and returns the attribute name if it was an attribute segment.

Trait Implementations

impl Clone for KeySegment

fn clone(&self) -> KeySegment

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeySegment

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

Formats the value using the given formatter.

impl From<&str> for KeySegment

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for KeySegment

fn from(s: String) -> Self

Converts to this type from the input type.

impl From<usize> for KeySegment

fn from(i: usize) -> Self

Converts to this type from the input type.

impl Hash for KeySegment

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for KeySegment

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