Struct Schema 

pub struct Schema {
    pub tables: Vec<Table>,
}

The complete database-level schema: a collection of tables.

Provides indexed access to tables, columns, and indices by their IDs.

Examples

use toasty_core::schema::db::Schema;

let schema = Schema::default();
assert!(schema.tables.is_empty());

Fields

tables: Vec<Table>

All tables in this schema.

Implementations

impl Schema

pub fn column(&self, id: impl Into<ColumnId>) -> &Column

Returns the column identified by id.

Panics

Panics if the table or column index is out of bounds.

pub fn column_mut(&mut self, id: impl Into<ColumnId>) -> &mut Column

Returns a mutable reference to the column identified by id.

Panics

Panics if the table or column index is out of bounds.

pub fn index(&self, id: IndexId) -> &Index

Returns the index identified by id.

Panics

Panics if the table or index offset is out of bounds.

pub fn index_mut(&mut self, id: IndexId) -> &mut Index

Returns a mutable reference to the index identified by id.

Panics

Panics if the table or index offset is out of bounds.

pub fn table(&self, id: impl Into<TableId>) -> &Table

Returns the table identified by id.

Panics

Panics if the table index is out of bounds.

pub fn table_mut(&mut self, id: impl Into<TableId>) -> &mut Table

Returns a mutable reference to the table identified by id.

Panics

Panics if the table index is out of bounds.

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 Default for Schema

fn default() -> Schema

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Schema

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

impl Resolve for Schema

fn model(&self, _id: ModelId) -> Option<&Model>

Returns a reference to the application Model with the specified ID.

fn table(&self, id: TableId) -> Option<&Table>

Returns a reference to the database Table with the specified ID.

fn table_for_model(&self, _model: &ModelRoot) -> Option<&Table>

impl Serialize for Schema

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
