Struct query_structure::ast::ModelId

pub struct ModelId(/* private fields */);

An opaque identifier for a model in a schema AST. Use the schema[model_id] syntax to resolve the id to an ast::Model.

Implementations

impl ModelId

pub const ZERO: ModelId = _

Used for range bounds when iterating over BTrees.

pub const MAX: ModelId = _

Used for range bounds when iterating over BTrees.

Trait Implementations

impl Clone for ModelId

fn clone(&self) -> ModelId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ModelId

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

Formats the value using the given formatter.

impl From<ModelId> for AttributeContainer

fn from(v: ModelId) -> AttributeContainer

Converts to this type from the input type.

impl Hash for ModelId

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

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 Index<ModelId> for SchemaAst

type Output = Model

The returned type after indexing.

fn index(&self, index: ModelId) -> &<SchemaAst as Index<ModelId>>::Output

Performs the indexing (container[index]) operation.

impl Ord for ModelId

fn cmp(&self, other: &ModelId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ModelId

fn eq(&self, other: &ModelId) -> 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 PartialOrd for ModelId

fn partial_cmp(&self, other: &ModelId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
