Struct Schema 

pub struct Schema {
    pub declarations: Vec<Declaration>,
    pub span: Span,
}

Top-level schema document containing all declarations.

Fields

declarations: Vec<Declaration>

All declarations in the schema (datasources, generators, models, enums).

span: Span

Span covering the entire schema.

Implementations

impl Schema

pub fn new(declarations: Vec<Declaration>, span: Span) -> Self

Creates a new schema with the given declarations.

pub fn models(&self) -> impl Iterator<Item = &ModelDecl>

Finds all model declarations in the schema.

pub fn enums(&self) -> impl Iterator<Item = &EnumDecl>

Finds all enum declarations in the schema.

pub fn types(&self) -> impl Iterator<Item = &TypeDecl>

Finds all composite type declarations in the schema.

pub fn datasource(&self) -> Option<&DatasourceDecl>

Finds the first datasource declaration.

pub fn generator(&self) -> Option<&GeneratorDecl>

Finds the first generator declaration.

Trait Implementations

impl Clone for Schema

fn clone(&self) -> Schema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Schema

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

Formats the value using the given formatter.

impl PartialEq for Schema

fn eq(&self, other: &Schema) -> 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.
