Struct FieldDefinition 

pub struct FieldDefinition { /* private fields */ }

Represents a definition of a field, which is comprised of its name, type of value, and any associated attributes

Implementations

impl FieldDefinition

pub fn new<N: Into<String>, T: Into<ValueType>>(name: N, type: T) -> Self

Creates a new field definition with the given name and value and no attributes

pub fn new_with_attributes<N: Into<String>, T: Into<ValueType>, A: IntoIterator<Item = FieldAttribute>>( name: N, type: T, attributes: A, ) -> Self

Creates a new field definition with the given name, value, and attributes

pub fn name(&self) -> &str

The name of the field tied to the definition

pub fn type(&self) -> &ValueType

The type of value of the field tied to the definition

pub fn attributes(&self) -> &[FieldAttribute]

The attributes associated with the field tied to the definition

pub fn is_indexed(&self) -> bool

Returns true if this field is marked as indexed (used in databases) in its definition

pub fn is_immutable(&self) -> bool

Returns true if this field marked as immutable in its definition and should not be updated

pub fn is_computed(&self) -> bool

Returns true if this field marked as computed

Trait Implementations

impl Clone for FieldDefinition

fn clone(&self) -> FieldDefinition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldDefinition

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

Formats the value using the given formatter.

impl<'a> From<&'a Field> for FieldDefinition

fn from(field: &'a Field) -> Self

Converts to this type from the input type.

impl From<Field> for FieldDefinition

fn from(field: Field) -> Self

Converts to this type from the input type.

impl PartialEq for FieldDefinition

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