Trait UpdateRecord 

pub trait UpdateRecord: Sized + CandidType {
    type Record: TableRecord;
    type Schema: TableSchema<Record = Self::Record>;

    // Required methods
    fn from_values(
        values: &[(ColumnDef, Value)],
        where_clause: Option<Filter>,
    ) -> Self;
    fn update_values(&self) -> Vec<(ColumnDef, Value)>;
    fn where_clause(&self) -> Option<Filter>;
}

This trait represents a record for updating a table.

Required Associated Types

type Record: TableRecord

The TableRecord type associated with this table schema.

type Schema: TableSchema<Record = Self::Record>

The table schema associated with this record.

Required Methods

fn from_values( values: &[(ColumnDef, Value)], where_clause: Option<Filter>, ) -> Self

Creates an update record from a list of column Values and an optional Filter for the where clause.

fn update_values(&self) -> Vec<(ColumnDef, Value)>

Get the list of column Values to be updated.

fn where_clause(&self) -> Option<Filter>

Get the Filter condition for the update operation.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
