Struct query_structure::SelectionResult

pub struct SelectionResult {
    pub pairs: Vec<(SelectedField, PrismaValue)>,
}

Represents a set of results.

Fields

pairs: Vec<(SelectedField, PrismaValue)>

Implementations

impl SelectionResult

pub fn new<T>(pairs: Vec<(T, PrismaValue)>) -> Selfwhere T: Into<SelectedField>,

pub fn add<T>(&mut self, pair: (T, PrismaValue))where T: Into<SelectedField>,

pub fn get(&self, selection: &SelectedField) -> Option<&PrismaValue>

pub fn values(&self) -> impl Iterator<Item = PrismaValue> + '_

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn db_names(&self) -> impl Iterator<Item = Cow<'_, str>> + '_

pub fn split_into( self, field_selections: &[FieldSelection] ) -> Vec<SelectionResult>

Consumes this SelectionResult and splits it into a set of SelectionResults based on the passed FieldSelections. Assumes that the transformation can be done.

pub fn as_scalar_fields(&self) -> Option<Vec<ScalarFieldRef>>

Checks if self only contains scalar field selections and if so, returns them all in a list. If any other selection is contained, returns None.

pub fn coerce_values(self) -> Result<Self>

Coerces contained values to best fit their type.

• Scalar fields coerce values based on the TypeIdentifier.
• Composite fields must be objects and contained fields must also follow the type coherence.

Trait Implementations

impl Clone for SelectionResult

fn clone(&self) -> SelectionResult

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SelectionResult

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

Formats the value using the given formatter.

impl Default for SelectionResult

fn default() -> SelectionResult

Returns the “default value” for a type.

impl From<&FieldSelection> for SelectionResult

fn from(fs: &FieldSelection) -> Self

Converts to this type from the input type.

impl From<&SelectionResult> for FieldSelection

fn from(p: &SelectionResult) -> Self

Converts to this type from the input type.

impl<T> From<(T, PrismaValue)> for SelectionResultwhere T: Into<SelectedField>,

fn from((x, value): (T, PrismaValue)) -> Self

Converts to this type from the input type.

impl From<SelectionResult> for Record

fn from(selection_result: SelectionResult) -> Self

Converts to this type from the input type.

impl<T> From<Vec<(T, PrismaValue)>> for SelectionResultwhere T: Into<SelectedField>,

fn from(tuples: Vec<(T, PrismaValue)>) -> Self

Converts to this type from the input type.

impl Hash for SelectionResult

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 IntoFilter for SelectionResult

fn filter(self) -> Filter

impl IntoIterator for SelectionResult

type Item = (SelectedField, PrismaValue)

The type of the elements being iterated over.

type IntoIter = IntoIter<<SelectionResult as IntoIterator>::Item>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for SelectionResult

fn eq(&self, other: &SelectionResult) -> 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 TryFrom<SelectionResult> for PrismaValue

type Error = DomainError

The type returned in the event of a conversion error.

fn try_from(return_values: SelectionResult) -> Result<Self>

Performs the conversion.
