Struct FieldKey 

pub struct FieldKey { /* private fields */ }

A field key is a valid key to a field.

This can be used for path parts keys, the parent key, etc.

Validation

• The key must not be empty
• The first character of the key must be any ASCII alphabetic character or _.
• The remainder characters must be any ASCII alphanumeric character or _.
• Sections can be split with .. The above rules then apply to each section.

Implementations

impl FieldKey

pub fn new(key: &str) -> Result<Self, Error>

Create a new field key.

pub fn as_str(&self) -> &str

Access the internal key string.

Trait Implementations

impl Clone for FieldKey

fn clone(&self) -> FieldKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldKey

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FieldKey

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

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for FieldKey

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

Formats the value using the given formatter.

impl Hash for FieldKey

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 FieldKey

fn eq(&self, other: &FieldKey) -> 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 FieldKey

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

Serialize this value into the given Serde serializer.

impl TryFrom<&FieldKey> for FieldKey

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: &FieldKey) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&String> for FieldKey

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: &String) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&str> for FieldKey

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for FieldKey

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self, Self::Error>

Performs the conversion.
