Represents a schema definition for a database sequence.

Fields

sequence_id: SequenceId

sequence_name: String

table_id: TableId

col_pos: ColId

The position of the column associated with this sequence.

increment: i128

start: i128

min_value: i128

max_value: i128

allocated: i128

Implementations

impl SequenceSchema

pub fn from_def(table_id: TableId, sequence: SequenceDef) -> Self

Creates a new SequenceSchema instance from a SequenceDef and a table_id.

Arguments

• table_id - The ID of the table associated with the sequence.
• sequence - The SequenceDef to derive the schema from.

Example

use spacetimedb_sats::db::def::*;

let sequence_def = SequenceDef::for_column("my_table".into(), "my_sequence".into(), 1.into());
let schema = SequenceSchema::from_def(42.into(), sequence_def);

assert_eq!(schema.sequence_name, "seq_my_table_my_sequence");
assert_eq!(schema.table_id, 42.into());

Trait Implementations

impl Clone for SequenceSchema

fn clone(&self) -> SequenceSchema

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SequenceSchema

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

Formats the value using the given formatter.

impl From<SequenceSchema> for SequenceDef

fn from(value: SequenceSchema) -> Self

Converts to this type from the input type.

impl PartialEq for SequenceSchema

fn eq(&self, other: &SequenceSchema) -> 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 Eq for SequenceSchema
