Enum NameSegment

pub enum NameSegment {
    Uuid(Uuid),
    Text(Ustr),
}

A segment in a qualified name.

A segment is either a meaningless, machine-generated identifier, represented as a UUID, or a meaningful, operator-generated name, represented as an interned string.

Variants

Uuid(Uuid)

A universally unique identifier (UUID).

Text(Ustr)

A human-readable name, assumed unique within the relevant context.

Implementations

impl NameSegment

pub fn serialize_string(&self) -> String

Serializes the segment into a string.

pub fn deserialize_str(input: &str) -> Result<Self, String>

Deserializes a segment from a string.

Trait Implementations

impl Clone for NameSegment

fn clone(&self) -> NameSegment

Returns a duplicate of the value.

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

Formats the value using the given formatter.

impl Display for NameSegment

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

Formats the value using the given formatter.

impl From<&str> for NameSegment

fn from(name: &str) -> Self

Converts to this type from the input type.

impl From<Ustr> for NameSegment

fn from(value: Ustr) -> Self

Converts to this type from the input type.

impl From<Uuid> for NameSegment

fn from(value: Uuid) -> Self

Converts to this type from the input type.

impl Hash for NameSegment

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,

impl<T> Index<NameSegment> for Row<T>

type Output = T

The returned type after indexing.

fn index(&self, index: FieldName) -> &Self::Output

Performs the indexing (container[index]) operation.

impl Ord for NameSegment

fn cmp(&self, other: &NameSegment) -> 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 NameSegment

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

fn partial_cmp(&self, other: &NameSegment) -> 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.
