Struct below_model::VecFieldId

pub struct VecFieldId<F: FieldId> {
    pub idx: Option<usize>,
    pub subquery_id: F,
}

Type that makes Vec Queriable if Vec’s inner type is Queriable. Uses idx to query into a Vec. Uses subquery_id to query into the selected item.

Fields

idx: Option<usize>

None is only for listing variants and otherwise invalid.

subquery_id: F

Trait Implementations

impl<F: Clone + FieldId> Clone for VecFieldId<F>

fn clone(&self) -> VecFieldId<F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<F: Debug + FieldId> Debug for VecFieldId<F>

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

Formats the value using the given formatter.

impl<F: FieldId> FieldId for VecFieldId<F>

where <F as FieldId>::Queriable: Sized,

type Queriable = Vec<<F as FieldId>::Queriable>

impl<F: FieldId + FromStr> FromStr for VecFieldId<F>

where <F as FromStr>::Err: Into<Error>,

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl<F: PartialEq + FieldId> PartialEq for VecFieldId<F>

fn eq(&self, other: &VecFieldId<F>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<F: FieldId + Sequence> Sequence for VecFieldId<F>

const CARDINALITY: usize = <<Self as DelegatedSequence>::Delegate>::CARDINALITY

Number of values of type Self.

fn next(&self) -> Option<Self>

Returns value following *self or None if this was the end.

fn previous(&self) -> Option<Self>

Returns value preceding *self or None if this was the beginning.

fn first() -> Option<Self>

Returns the first value of type Self.

fn last() -> Option<Self>

Returns the last value of type Self.

impl<F: FieldId + ToString> ToString for VecFieldId<F>

fn to_string(&self) -> String

Converts the given value to a String.

impl<F: FieldId> StructuralPartialEq for VecFieldId<F>
