Enum Dialect 

pub enum Dialect {
    Sqlite,
    Postgres,
}

Selected at compile time via the postgres feature flag. Dialect::CURRENT resolves to the active dialect.

Variants

Sqlite

Postgres

Implementations

impl Dialect

pub const CURRENT: Dialect = Dialect::Sqlite

The dialect selected at compile time.

pub const fn as_str(self) -> &'static str

pub fn param(self, index: usize) -> String

Positional parameter placeholder for this dialect.

SQLite uses ?N, Postgres uses $N.

pub fn map_default(self, default: &str) -> String

Translate SQLite-specific default expressions to their Postgres equivalents.

Unknown defaults pass through unchanged.

pub const fn now_epoch(self) -> &'static str

SQL expression for the current Unix epoch in seconds.

Postgres: extract(epoch from now())::bigint; SQLite/libsql: unixepoch(). Use this instead of hardcoding the Postgres form in raw SQL / set_expr.

pub fn quote_ident(self, ident: &str) -> String

Quote a SQL identifier (table name, column name).

Both SQLite and Postgres use double quotes for identifiers.
