Struct FieldName 

pub struct FieldName(/* private fields */);

A single dotted path (e.g. "database.url" or "a").

Created for you by Foo::fields().some_field().

Implementations

impl FieldName

pub fn as_str(&self) -> &str

Get the dotted string path (borrowed).

pub fn static_lit(lit: &'static str) -> Self

Build a Field from a &'static str literal with zero allocation.

pub fn from_string(s: String) -> Self

Build a Field from an owned String (one allocation already paid).

pub fn join(prefix: &str, key: &'static str) -> Self

Append key to the (possibly empty) prefix.

Trait Implementations

impl AsField for FieldName

fn as_field(&self) -> FieldName

impl Clone for FieldName

fn clone(&self) -> FieldName

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldName

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

Formats the value using the given formatter.

impl Eq for FieldName

impl Hash for FieldName

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 FieldName

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