Struct Schema 

pub struct Schema {
    pub tables: Vec<TableDef>,
    pub enums: Vec<EnumDef>,
}

A whole application schema: every #[derive(Table)] struct and #[derive(DbEnum)] enum found in the tables folder. Tables and enums are kept sorted by name so snapshots are deterministic regardless of file ordering.

Fields

tables: Vec<TableDef>

enums: Vec<EnumDef>

Implementations

impl Schema

pub fn table(&self, name: &str) -> Option<&TableDef>

pub fn merge(&mut self, other: Schema, source: &str) -> Result<(), Error>

Adds another schema’s tables and enums — how a module’s shipped snapshot joins the app’s schema before diffing. source names the module for error messages.

Errors

A table name that already exists, or an enum of the same name with different values, is a hard conflict.

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 PartialEq for Schema

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

Equality operator ==.

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

Inequality operator !=.
