Trait leetcode_tui_rs::migrations::sea_orm::ColIdx

pub trait ColIdx: Debug + Copy {
    type SqlxSqliteIndex: ColumnIndex<SqliteRow>;

    // Required methods
    fn as_sqlx_sqlite_index(&self) -> Self::SqlxSqliteIndex;
    fn as_str(&self) -> Option<&str>;
    fn as_usize(&self) -> Option<&usize>;
}

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

Required Associated Types

type SqlxSqliteIndex: ColumnIndex<SqliteRow>

Type surrogate

Required Methods

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
