Struct TypedField 

pub struct TypedField<Record, Value> { /* private fields */ }

Compile-time metadata for one strongly typed query field.

Implementations

impl<Record, Value> TypedField<Record, Value>

pub const fn new(field_id: u32, name: &'static str, indexed: bool) -> Self

Constructs generated field metadata.

pub const fn field_id(self) -> u32

Returns the stable numeric field ID.

pub const fn name(self) -> &'static str

Returns the declared Rust field name.

pub const fn is_indexed(self) -> bool

Returns whether the schema materializes a secondary index.

pub fn eq(self, value: impl Into<Value>) -> EqualityFilter<Record>

where Value: RecordKey,

Builds a type-checked equality predicate.

pub fn lt(self, value: impl Into<Value>) -> RangeFilter<Record>

where Value: RecordKey + Ord + Send + Sync + 'static,

Builds a type-checked less-than predicate.

pub fn le(self, value: impl Into<Value>) -> RangeFilter<Record>

where Value: RecordKey + Ord + Send + Sync + 'static,

Builds a type-checked less-than-or-equal predicate.

pub fn gt(self, value: impl Into<Value>) -> RangeFilter<Record>

where Value: RecordKey + Ord + Send + Sync + 'static,

Builds a type-checked greater-than predicate.

pub fn ge(self, value: impl Into<Value>) -> RangeFilter<Record>

where Value: RecordKey + Ord + Send + Sync + 'static,

Builds a type-checked greater-than-or-equal predicate.

Trait Implementations

impl<Record, Value> Clone for TypedField<Record, Value>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Record: Debug, Value: Debug> Debug for TypedField<Record, Value>

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

Formats the value using the given formatter.

impl<Record: Hash, Value: Hash> Hash for TypedField<Record, Value>

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<Record: PartialEq, Value: PartialEq> PartialEq for TypedField<Record, Value>

fn eq(&self, other: &TypedField<Record, Value>) -> 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.
