Struct FieldSelector 

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

A field selector label for extracting document fields.

Implementations

impl FieldSelector

pub fn new(value: impl Into<String>) -> Self

Creates a new string-backed primitive.

pub fn as_str(&self) -> &str

Returns the stored string value.

Trait Implementations

impl AsRef<str> for FieldSelector

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for FieldSelector

fn clone(&self) -> FieldSelector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldSelector

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

Formats the value using the given formatter.

impl Default for FieldSelector

fn default() -> FieldSelector

Returns the “default value” for a type.

impl Display for FieldSelector

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

Formats the value using the given formatter.

impl From<&str> for FieldSelector

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for FieldSelector

fn from(value: String) -> Self

Converts to this type from the input type.

impl Hash for FieldSelector

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 Ord for FieldSelector

fn cmp(&self, other: &FieldSelector) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for FieldSelector

fn eq(&self, other: &FieldSelector) -> 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 PartialOrd for FieldSelector

fn partial_cmp(&self, other: &FieldSelector) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
