Column Index, used by TryGetable. Implemented for &str and usize

Required Associated Types

type SqlxMySqlIndex: ColumnIndex<MySqlRow>

Type surrogate

type SqlxPostgresIndex: ColumnIndex<PgRow>

Type surrogate

type SqlxSqliteIndex: ColumnIndex<SqliteRow>

Type surrogate

Required Methods

fn as_sqlx_mysql_index(&self) -> Self::SqlxMySqlIndex

Basically a no-op; only to satisfy trait bounds

fn as_sqlx_postgres_index(&self) -> Self::SqlxPostgresIndex

Basically a no-op; only to satisfy trait bounds

fn as_sqlx_sqlite_index(&self) -> Self::SqlxSqliteIndex

Basically a no-op; only to satisfy trait bounds

fn as_str(&self) -> Option<&str>

Self must be &str, return None otherwise

fn as_usize(&self) -> Option<&usize>

Self must be usize, return None otherwise

Object Safety

This trait is not object safe.
