Enum query_structure::ast::TopId

pub enum TopId {
    CompositeType(CompositeTypeId),
    Model(ModelId),
    Enum(EnumId),
    Generator(GeneratorId),
    Source(SourceId),
}

An identifier for a top-level item in a schema AST. Use the schema[top_id] syntax to resolve the id to an ast::Top.

Variants

CompositeType(CompositeTypeId)

A composite type

Model(ModelId)

A model declaration

Enum(EnumId)

An enum declaration

Generator(GeneratorId)

A generator block

Source(SourceId)

A datasource block

Implementations

impl TopId

pub fn as_enum_id(self) -> Option<EnumId>

Try to interpret the top as an enum.

pub fn as_model_id(self) -> Option<ModelId>

Try to interpret the top as a model.

pub fn as_composite_type_id(&self) -> Option<CompositeTypeId>

Try to interpret the top as a composite type.

Trait Implementations

impl Clone for TopId

fn clone(&self) -> TopId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TopId

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

Formats the value using the given formatter.

impl Hash for TopId

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<TopId> for SchemaAst

type Output = Top

The returned type after indexing.

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

Performs the indexing (container[index]) operation.

impl Ord for TopId

fn cmp(&self, other: &TopId) -> 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 TopId

fn eq(&self, other: &TopId) -> 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 TopId

fn partial_cmp(&self, other: &TopId) -> 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.
